I have 4TB of old movies recorded from television without commercials, a collection that I expect will entertain my wife and I into our old age (and we're not that far from that now). They were recorded on Panasonic and Magnavox hard drive recorders in DVD format, which is SD 720x480 with NTSC pixel ratio 10:11, meaning they are all 4:3 aspect ratio in spite of the 720x480 resolution.
Now I would like to convert these to MPEG4 H.264 to save space on my HTPC, a 2010 Mac Mini that I have on order. My main PC is now a Dell, but will be a Mac Pro if they ever update it, so I'm keeping my originals in MPEG2 just in case I make a mistake in the conversion. I'd like to save at least 1TB of space, and in testing some conversions I can do that with H.264 640x480 with pixel ratio 1:1. If I try to keep the video at 720x480 so as not to lose any resolution from the original, the video is played "stretched" at an aspect ratio of 3:2 instead of 4:3 because the MPEG4 file doesn't recognize the 10:11 pixel ratio of NTSC SD.
So, is there a work-around to save the full resolution of the originals, or do I have to use 640x480? Just for laughs, I tried 720x540 (4:3 with pixel ratio 1:1), and the videos looked very good and displayed correctly. But can I use my own "invented" resolution to play movies on OS X?
