Best Quality settings to convert DVD's to ATV

For DVDs, I use Handbrake and have seen truly excellent results:

For other video files, I've used Videora. It works okay, but there are probably better things out there:

Let us know what you go with.

you'll need to experiment for your storage capability. I use 2500 bit rate and the "normal" file size for a two hour movie is about 1.7 to 2.3 gigs

Picture is very near the original source and the file size is manageable.

Hope this bit of info helps also...
The default bitrate when using the ATV preset on Handbrake is 2500kbps, which for a 2 hour movie is about 2+GB
I tweaked the bit rate ripping Raiders of the Lost Ark at 1000kbps then 1500kbps and finally at the default, 2500kbps. The 1500kbps was totally fine and saves you over a gig space. I think the final file size for Raiders at 1500kbps was 956 megs as opposed to 2.13BG for the default setting on Handbrake.
I watched the 2500kbps (Apple TV preset) vs the 1500kbps (custom) and unless you're a REAL CRAZY videophile you can't tell the difference.
