The Android operating system supports MPEG4 Advanced with the h.264 codec, I suggest using the default settings on
Rip DVD Plus for this codec.
Keep the dimensions the same as the original DVD, 720x480, and a 3000kbit bit rate. This should give you excellent results on your Android tablet. Ripping on your Windows 7 PC with these settings will give you a better quality video -- and it will definitely take a lot less time.
