I wanted to watch some videos that I have on my USB flash drive on my Xbox 360. I got this Xbox for Christmas last year, so it is fairly new, and it has all the updates. When I tried to play the video on the Xbox, an error came up and said that the file type was not supported. I already have the Optional Media Update, so I should be able to play MP4s and AACs, but it won't let me. I have not experimented with WMVs or any other video type yet...
What can I do to fix this problem?
