I decided to get MacX DVD Ripper Pro. I am ripping/moving stuff from disc to HD for my AppleTV3 library. Current display device is Sony 34" HDTV (KVSH510). The first few discs I have been just putting them in and using the toAppleTV default. That would be 640x360 Wide-Screen mp4 Good Quality. There was also a 1280x720 Wide-Screen H264 High Quality. When I tried using that, the output looked slightly stretched and the quality wasnt as good as the 640 when I compared the same title side by side. That anime (Ghost in the Shell) was 4x3 original source. Since those were mostly animated stuff (Heavy Metal, anime), I wasnt too particular. The output quality looked fine on AppleTV3 defaults. Now I started ripping some 60/70s movies (Harry Palmer), and I had noticed that in a lot of cases, MDRPro was identifying then as 720x480 16x9. I let Funeral in Berlin get encoded as 640x360 with the AppleTV default. Now instead for Billion Dollar Brain I selected MP4, it defaults to a higher quality setting (using 1800 kps instead of 1500 bps). In addition, it keeps the video width at 720. Billion Dollar Brain looks good and so does Now, should I in general be using the MP4 setting instead, since it seems to be matching the resolution, and not reencoding for a different resolution?
