Questions about MacX DVD Ripper Pro

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?

Thanks for the responses.

I have Handbrake, MKV and MacX DVD Ripper Pro.

It just seemed so easy to pop it in and let MDRP rip and give me an MP4 in one step.

I have read (parts of the) automated DVD ripping and converting sticky in this category.

Yeah, I want the best quality in the rip overall, was just finding my way through these different products..
