PAL standard should be 720 x 576 resolution and 25fps frame rate. Audio is probably AC3, but might be MP2, which is not used in NTSC standard dvds.
Are these what you see in MediaInfo?
If so, you might want to reencode the video to NTSC standards. AVStoDVD should be able to do this (fingers crossed). http://www.videohelp.com/tools/AVStoDVD In any case it is free to use. Make sure to set the video output to NTSC in Preferences. Import the dvd into AVStoDVD by clicking on the green + sign, and selecting the VTS_01_0.IFO file in your dvd.
You will lose the original menu doing this, but you can build a new one in AVStoDVD if you want....it may be much more crude, but will function. You don't have to make a menu if it is not desired.
