So, as far as I can tell by searching on google - everyone says Xbox 360 has Xvid (.avi) support. I've even seen some claim the 360 plays .mkv ....
Now, I know how to do it, and I have even gotten some files to play. But most of them are unplayable. The icon is a crossed-thru 'Stop' sign.
And IIRC I downloaded that media updates ages ago.
Why can't I play video files with ease?
The reason I am having this issue, now, is because I used to use my PS3 solely for media (no Netflix paywall, if Im using my Gold), and Xbox for gaming, but now I have that at my GF's cause I want my two Xbox 360s at home for GTA V.
I am 99% certain I just need to go back to using PS3 for media, cause it plays practically everything (every Xvid, avi that is) flawlessly.
