I use the free version of MediaCoder http://www.mediacoderhq.com
with these settings in the audio section: http://img5.fotos-hochladen.net/uploads/mediacodersettim2z70sxr8o.jpg
Only converts the audio tracks. Takes only a few minutes to do a whole movie.
Forgot to say: If its not default setting, check "Copy Video" in the Video section.
Download MediaCoder it is basically a GUI front end to ffmpeg.

This is just NVENC. I'm assuming OP has never heard of MediaCoder which supports other HW Encoding with CUDA or QuickSync.
It's been a while since I've paid attention to the encoding scene, I think more people are using Handbrake now (which supports AMD's VCE).
I use MediaCoder to drop files in and analyze their codec information then decide if I need to re-encode them. It's kind of expensive if you want all the features but the free version has some handy abilities.
Generally I encode in a H.264 High Profile at 4.1 or lower (I've tried 5.0 and it for some reason won't play audio). Then I use a high quality AAC audio codec. Then I use a slow preset to get the best quality per bitrate. It takes a bit longer but I'm only going to encode it once and watch it a lot of times.
mkvtoolnix only wraps up audio & video streams (and subtitles, chapter marks, etc.) in a container file. You need to identify the actual video stream within the original .avi, check its compatibility with your player, and find a better format to convert it to. Once you've identified it, Media Coder can handle the actual conversion.
Also keep in mind that the transcoding might not be what's causing your issue - It could easily by your network or the host box. What kind of hardware are you using to serve up the videos? Is it regularly topping out available CPU time on simple tasks like transcoding? Does your server software provide a readout of how much of a buffer is available for transmission? How are you streaming to your Roku? Is it over wired ethernet, or wireless? If it's wireless; is it g or n, how many other devices are on the network, is your router model known for having issues with high-bandwidth media streaming?
I personally used to get similar issues with streaming anything above SD on my network from a 3.4GHz quad-core box, and eventually traced it back to the fact that I was streaming HD over wifi in a house with a dozen other devices on the network. Switching to wired ethernet fixed that for me, though it required buying a pair of powerline ethernet adapters.
http://www.mediacoderhq.com/ or http://handbrake.fr/ both have pretty friendly GUIs.
Keep in mind that .avi is not a video format in and of itself, it is a container format that holds audio tracks (mp3 usually) and video tracks (xvid usually) and interleaves them so they stay in sync as you play the file.
If I am not mistaken mediacoder will do the job.

I use MediaCoder. http://www.mediacoderhq.com/
It's pretty much just a GUI front-end for a WHOLE BUNCH of different transcoding projects. I like it because there are so many options to configure around with. You can play with subtitle size, the way you want audio to work out, resolution, it's AMAZING. It's kind of like torrents in that it looks hard to use, but trust me, it's actually really nice to be able to convert between really obscure file formats. Plus, you can use it to batch-convert a whole shitton of videos.
I use MediaCoder. Download the full version and its free. This program has presets for almost any device. MediaCoder can use an NVidia GPU (CUDA) to convert the videos. I use this for my ZuneHD to convert full length movies in about 30min.
You sure the crashing isn’t a hardware/software problem on your end? In my experience Handbrake has been very stable and video encoding is the sort of task that can really get unstable hardware to crash.
But if you want to try something else there’s MediaCoder. I wouldn’t consider it as easy to use as Handbrake but it can create high quality video just as well as Handbrake can.
You're going to have to convert them to a very specific format unfortunately. Also, the Zune software's native converter was removed a few years ago in Windows 10 (Windows 7 still has it). I had decent luck with MediaCoder to use as a stop-gap.
I made these preset templates for MediaCoder:
It's a user interface language made by Mozilla. It's not necessarily insecure but Mozilla transitioned to using html5 for their UI programming language rather than their own in-house maintained language and also migrated to web extensions for their add-ons instead of using XUL-based add-ons.
For add-ons, they are lighter weight and they are more limited in what they can do. For example, XUL- based add-ons could actually manipulate Firefox's user interface. Some people got upset that they could no longer do some things like that but the trade-off was for more performance, more security (since an add-on can't do quite as much) and webextensions are cross-compatible with Google Chrome extensions. So a Dev could more easily make something that works on both browsers (and Opera, and the new MS Edge browser)
There are a few forks of Firefox still hanging onto XUL and even a few desktop apps that use it. I think Thunderbird might still use it, Palemoon browser, and mediacoder http://www.mediacoderhq.com/ still use XUL.
Once Kodi gets better at playing 4K media you wont really have this issue, the stock video player on Xbox only plays AC3 (Dolby) audio.
Download MKVtoolnix and run it
Drag and drop in video, if AC3 (dolby) audio track is present select it then from the right hand side were it says "Default track flag" set it to yes.
Click start multiplexing to generate a new copy of the video with the AC3 track as default audio.
If the video has no AC3 audio track you must make one, however that is not so easy to do for some.
The "quickest" way I know is via MediaCoder.
Load in a video, on video tab tick the box to "copy video"
On the audio tab you must select the correct audio track to convert, set the "format = AC3" bitrate should not exceed 640kbps
On container tab set it to MKV then click on start.

Yes if you are talking about Plex then hardware acceleration is a Plex Pass feature only but you were talking about converting your files.
There are many programs that convert video from h265 to h264 using a GPU ahead of time before you put them into Plex.
MediaCoder is one of them.
Try MediaCoder Audio. FormatFactory also comes to mind. And, from a quick Google, Freemake Audio Converter.
I'm not sure about hvec but if any program would do it it would be MediaCoder (http://www.mediacoderhq.com/) . MC supports ALL kids of encoding others dont, like vbr and 2 pass GPU encoding. it's quite a pain in the ass to use though. not for amateurs.
Like I say I'm not sure about hvec, I still prefer h264 for the time being anyway but open cl apparently rips on some of the newer amd cards.
on a side note Handbrake sucks and is buggy as shit, it has a few features that are kind of usefull, but for general encoding Avidemux is much better.
There exists a free codec called Real Alternative which works: http://www.free-codecs.com/download/real_alternative.htm (Windows only and not open source). I can confirm this has worked with the aduni videos before.
MPlayer (open source and cross platform) is supposed to be able to view real media files, possible with the addition of Binary Codec Packages available for download on their downloads page. http://www.mplayerhq.hu/
Media Coder is supposed to be able to convert real media files into other formats if you want to archive them in a more open format. I haven't tested it with any real media files though. (Cross platform, previously open source but not any more) http://www.mediacoderhq.com/
Try this: http://www.mediacoderhq.com/
Never failed for me.
Be sure to enable Quicksync encoding if you have Intel HD Graphics 4000 or later, because it will greatly reduce encoding time. For me, it increased the conversion FPS from 150 (CPU-only) to 500.
If you have an Nvidia GPU, you can enable the NVENC feature, which is similar to QuickSync, but not quite as fast.
Free apps I've used for this include MediaCoder and FormatFactory, the latter is probably easier but less powerful. Just make sure not to select any adware during the install.
Have you tried this? It seems to support plenty of formats, but I mostly used it for the Intel Quicksync support. It also supports CUDA acceleration, which is nice.
There's also SUPER, which supports virtually any video format.
Using the hardware H.264 encoder of your graphics card is really the best way to record and encode the footage on-the-fly. Dump_King mentioned Nvidia's Shadowplay. For AMD graphic adapters the corresponding solution to that would be any recording software that uses AMD's APP. My recommendations are Mirillis Action! and Bandicam. However, if you plan to edit your footage anyways, you might want to encode after you're done editing. For encoding only I found MediaCoder to be the easiest to use.
Try MediaCoder before you upload to youtube http://www.mediacoderhq.com/
Choose a .mp4 container and use H.254 for video and AAC for the audio. Play with the mbps rate. There's a wizard so the programs pretty easy to setup, but if you're confused i'm sure there's a ton of tutorials on how to use it.
Almost, not quite. His TV only supports .mpg (MPEG1/2), and Handbrake uses MPEG4/H.264. I reiterate, MediaCoder would be the better option, just select mpg as the output format.
I second this.
Definitely grab all of Star Trek: The Next Generation, and Firefly.
If you have the time, whatever you grab, transcode it into the smallest size you can so you can fit more on it. Follow this to choose. I'm thinking H264. And you can use MediaCoder though it's a bit annoying.
Other good nerd shows: Futurama, The Big Bang Theory, Doctor Who (the ones with Amy Pond), MythBusters, and Avatar: The Last Airbender (if you like anime). (Futurama and Avatar are probably the most efficient in terms of size, being cartoons.)
Also make sure you have a large music library, perhaps include some classical compilations to "culture" yourself.
Edit: fixed links.
This should be able to transcode it to a format you can use:
