Thanks Hello! Sorry to get back so late.

Well, I'm looking at Doctor Who stuff again, and it looks like most have the BBC blanking. About 12 to 13 pixel columns of black on each side. I still have a hard time finding a decent circle to look at though, and some just don't come out whether I use non-ITU, ITU, or BBC Blanking PARs. Finally found a good circle at the beginning of "The War Games" Disk 2, where they shoot some kind of force field out, and its a bunch of blurry circles. Looks like Ghitulescu may be right about the 788 stretch, as it only looks circular if you stretch it out to 788.

EDIT: In the end, after a lot of circle testing, I decided on going with 720x788 for Doctor Who. PAR for 720 x 788 is 197:180. I cropped it to 704 x 572 (cropping doesn't affect PAR), then went with a PAR of 197:180, to get 704 x 770, which seemed to give the best circles. Doctor Who NTSC videos, 720x480, seem to be ITU, with a 10:11 PAR, which produced the best circles.

There do seem to be parts of Doctor Who sometimes that appear to be 720 x 864, but examination of the rest of video shows circles at this DAR to be wildly off. You should stick with 720x788.

Thanks for your help guys!
