Can't speak for the others who do it, but this season I've got it set up so I can record the games from my cable with PVR software, and use my PC as a DVR. So for me, I have the game sitting on my hard drive as a video file; I just grab from that. Then I upload the video to Gfycat, nothing else needed.
You should be able to use any old TV software with it as long as Pinnacle didn't completely fuck up the drivers. Windows Media Center is great if available (XP MCE, higher end versions of Vista or 7), otherwise check out options like NextPVR
I've got one of these with NextPVR running as a backend server for XBMC/Kodi and it works a treat, I've also got a USB DVB-S dongle to grab satellite channels as well, so all my movies, TV series and live TV all run from XBMC with one remote to make it all very wife friendly)
Aerial wise I've got a cheapy external one from Aldi
I use USB because I'm running it all one one of those little Atom Ion powered nettop jobbies
Silly question -- you are running NextPVR, right? The plugin defaults to localhost, but if your NextPVR installation is on a different machine you'll have to change that in the addon options.
Do you want to keep TV? Does your cable provider copy protect any channels that you care about?
If you want to keep TV and have to deal with copy protected channels, then Win7 or Win8.1 Pro w/ WMC are the only ways to go (good luck finding a copy of WMC for 8.1 -- there were discs sold, but it was mostly a digital purchase/download and those servers were shut down a long time ago; you might have some luck on Ebay, but it'll cost you).
If you want to keep TV and don't need copy protected channels, then I'd install Windows 10 and NextPVR with Kodi as a frontend. NextPVR supports Ceton cards out of the box (you might need to grab this nshared.dll if you get crashes trying to bulk map), and I believe Ceton's win8 drivers work with win10. You'll need a Schedules Direct subscription ($25/year) for guide data. And I'd recommend in Kodi making sure you set the PVR configuration to use server-side channel maps so you don't get confused.
I'm still using 8.1 Pro and WMC, but after yet another guide data scare last weekend I went ahead and got NextPVR set up. I need to train my in-laws on how to use TV in Kodi, and then I'll upgrade to Win10 and switch over the npvr and Kodi and kiss WMC goodbye forever. Tentative timeline is to get that done in July, giving me time to get a decent extender replacement set up (probably will do an rpi3 and flirc or a wmc USB IR receiver).
Otherwise, it seems HDHomeRun is the way to go these days, but that would be a new hardware investment when you've already got a perfectly good tuner, and it's a downgrade. SD still maxes out at 3 tuners per m-card, despite m-cards allowing up to 6 (Ceton has a 6-tuner device; SD's "6-tuner" device was just two 3-tuners glued together, requiring two cablecards which are the weakest link in the chain). IMHO, I'd rather cut the cord entirely than switch to HDHR.
Just drop a TV tuner card in your computer and slap an antennae on the back.
The only thing that makes this difficult is the confusing array of options. You want a TV tuner card that supports at least 1080i, although 1080p or 4K can't hurt.
Then you need a PVR program of some kind. That tutorial recommends NextPVR, which looks simple.
When its all said and done, it costs about $150 to upgrade your computer to record the content directly, and the resulting video will be more portable and higher quality.
if your running windows take a look at mediaportal and NextPVR If your tuning OTA the world is yours dude. ATSC is supported completely in basically all PVR clients.
i haven't looked into setting it up on my x1 since the dlna updates, so i can't speak to where things stand on that front. as someone who has been using an hdhomerun prime for the last 2 years though, i can speak as to the device itself, and it's awesome.
i got it for the same reason you cited (i was paying $20 month in cable box rentals that didn't support dvr, where as a single cable card was only $4/month)
you mentioned wanting to use an x360 with it, however the x360 isn't going to interface very well with this device due to the x360 only having partial dlna support.
what i do is that every tv in my house is connected to a computer, and each of those computers is running npvr as a backend and xbmc (ignore their pending and retarded name change to "kodi", it's all the same program) as a front end.
with this setup, i'm able to watch live tv with dvr support on all of my tv's, and i can use my phone as a remote (since it's able to control xbmc via wifi). just remember that if you want epg (your tv guide) to be properly functioning, you just have to setup a quick batch script to run nightly and automatically update your local copy of the tv schedule.
my personal experience was that it was a little bit complicated to get the initial setup working, but once everything was up and going, it was rock solid and provided a great experience. for my initial testing, i used windows media center and this provided for a very easy setup, however i find it hard to recommend a setup that hinges on software we know microsoft is in the process of phasing out/abandoning.
if you aren't able to get the hdhomerun prime working natively with your x1, you at the very least will have the option to toss a raspbery pi/old laptop/old desktop/etc. into the hdmi in port to get the x1 interfacing with it that way.
It you want a computer based DVR check out hdhomerun with their own DVR service. Or use plex with it. I am fond with http://www.nextpvr.com/
Used next DVR for years back when it was gbpvr.
Problem is hdhomerun is the only one that will in the near future play protected channels.
I think SageTV deserves a spot in the HTPC Software section. It's Open Source now, had matured enough for public consumption again, and is a really solid DVR package.

According to this, IPTV support was removed from v2.5.9, so if you're using something newer than that, it won't work.
It doesn't look like there support for IPTV was great to begin with though.
If you want to use the PVR feature in Kodi, try following this guide: https://www.reddit.com/r/Addons4Kodi/duplicates/5vt55d/guide_clean_and_pure_kodi_iptv_setup_guide_with/
It worked great for me.
I asked about various setup differences over on r/FabIPTV and the mod there actually mentioned integrating their addon with IVUE, so that's an option as well.
You'd need a TV tuner card in your PC to do that, but yes. And you could do it without paying, just not through the Roku app. You just install a plugin to interface with DVBLink, Media Portal, NextPVR, or Windows Media Center, depending on which you are running.
NextPVR is a great alternative to WMC. Paired with certain extenders, it offers a nice solution.
As will all computer based DVR recorders, there are issues and compromises. The cable companies make it fucking ridiculously difficult at times...
