Hi. I recently purchased a Pioneer DV-563AS and discovered that Region 0 DVDs can be played on them and the PAL output would be changed to NTSC. I have some Region 0 discs that were burned. Of them, two will not play in the Pioneer player. The player loads the disc and then goes to "STOP" on the display. When I try to play them on my PC's DVD-ROM drive, they work fine. However, I have noticed that they have different menus then the other ones. Could that be the problem and, if so, is there anything that I could do to get them to play? Any help would be greatly appreciated. Thanks.
