This has been a great unit! It has played just about anything I put in it for 3 months. Now it will still play VCD/SVCD/XVCD; but only for 3 seconds. After 3 seconds of play, the screen freezes for 5 seconds, and the player stops. This isn't just recently burned disks. It happens on disks that previously played perfectly. I haven't applied any hacks, cracks, or attempted to modify the unit in any way. CD/DVD playback is still perfect. Any ideas??
