Okay, now another problem - I think. When previewing my newly created PAL DVD, all video looks streched, which I assume is due to the fact that PAL has more horizontal lines. How can I keep the aspect ratio the way it should be, in the NTSC format? I see the different Video Arrange Methods in TMPG but they don't seem to have any effect that I can tell, it still looks stretched when viewing the DVD through PowerDVD on the computer no matter what method I choose, accept for Center (keep aspect ratio) which has black all around the clip. I accidentally set the source type as PAL when I converted one of my clips to the PAL format and it has black bars at the top and bottom and appears to preserve the original aspect ratio. Is this what I need to do to keep the aspect ratio or am I missing something?

Thanks,
Andrew
