My jtagged xbox 360 wont play any videos, i've tried wmv, and avi but it wont play any. When i choose a video to be played it just hangs at a black screen, i can bring up the controls, like play, pause, fast forward, etc, but no video actually plays. I hope someone can help. Could it have been a bad flash? I'm trying to play videos off a usb thumb drive. At first i thought that maybe it was the thumb drive so i tried it on my cousins 360 and it played vifrod just fine.
