Yes, but you'll also want to get the media remote to have better control over playback.

More expensive but this is a bluetooth remote and can work just about any menu on the PS3. It can also turn on the PS3 from standby. I own this and feel it really makes rhe PS3 a true media device. If it matters, it 'feels' good (well built).
Also does not hurt that it is THE official PS3 media remote.
You can also get a remote designed specifically for playing back DVDs. It's so much better than trying to use a controller.
I have an st60, whats the issue with the usb not working for files? Side note, that's a great tv for people with seemingly no technical knowledge.
From what you've said, I think your best option is buy a new hard drive and swap out the old one in that ps3 and buy a remote like this for your parents. Its quite easy to use, my folks used that for a long time, with MKVs becoming more and more prevalent, it became more annoying, they use their iphones to send it to the apple tv now (wasn't easy to teach them but they got the hang of it)
What else do they have, a computer? phones?
Who wants to wait for a fucking video game controller to turn on and connect when I want to pause a program right now? Or I could leave an unsightly cable hanging out of my PS4 all the time for charging. My media center is pristine, I don't want dangling cables up in my shit. Not to mention I'm on my third PS4. Boo that. Roku is awesome. Way more convenient, very reliable, and super cheap. The remote for the PS3 Blu Ray remote was so awesome. I was so bummed when they didn't have something similar for the PS4.
I think if you're at the point where you're stepping in every time you should just pick up the remote.
I always felt the controller functions were mapped really well. R1/L1 chapter skip, R2/L2 fast forward/rewind, Start pauses and resumes on DVDs and Blurays and X pauses and resumes on divx/avi files. Just makes sense.
Still only $25, I seem to remember it being more when at the stores, although $50 may have been a bit of an exaggeration. Point still stands though, just sayin'.

I believe that works for the device.
$20 "blu-ray" Remote, best investment you can get if you're anywhere close to serious about watching movies on your PS3.
Yes it is. I think mine may have been included with my first PS3 but I could be wrong. Also I'm pretty sure you can use a universal remote with the PS3.
I wonder if a PS3 bluetooth remote would work well? They are not expensive and don't use up the USB slot.
