Make sure the codec of your DVD disk is MPEG2 or it can never be read. Download HandBrake [http://www.videoconverterfactory.com/tips/is-handbrake-safe.html] and after you go into the program, choose MPEG2 as the output, then burn the video to a blank disk and insert again to XBOX360. Or you can try another simpler way. In the selection list on the right side, you can choose the output format of XBOX360, MP4 H264, i think and stream the disk content to a USB and insert the usb to the XBOX usb jack for playback.
