[quote name='thrustbucket']I've had weird issues with .mp4 files. I have been able to play them from a usb flash, but not over my network with my pc. It doesn't even seem to see them over the network.
And yes, you do new the codec update, but usually the prompt for that to install occurs when you try to play an avi/mp4 file.
Luckily I always avoid mp4 files like the plague so it really isn't an issue.[/QUOTE]
I'm asking if you need a codec update for your PC? I have made no changes to my 360 except the NXE download. I was thinking .mp4 support was added or something. Maybe I downloaded the Vista codec pack. Since my computer should be no different than my friend's PC, only the fact that i downloaded a bunch of programs to convert videos from mkv, etc.
My Xbox actually recognizes the .mp4 in my video library of my Xbox 360, which was surprising to me.
I usually just change the .mp4 extension to .avi, but now all my .mp4s show up I actually don't have to dodge them anymore
