I have 3 - :30 spots at 720x480 that Time Warner has requested as MPEG 2.
The quality of the conversion using Compressor is rather nice, taking a 1.33 gig QT file and compressing it down to about 50meg.
The problem is that it's squeezing the 720x480 ratio down to 640x480 and I can't figure out how to make it keep the file at 720x480.
I'm using the MPEG-2 Program Stream setting in compressor. I've also tried duplicating it and the summary setting indicate 720x480 NTSC CCIR for the pixel aspect ratio. Aspect Ratio is 4:3
