VoB or MKV

What better of the two...Thanks

MKV is a more sophisticated container format. What are you wishing to do?

I assume you are talking about from a DVD.

VOB - No quality loss, large file size.
MKV - Quality versus file size dependent on the bitrate chosen (never lossless, but you might not be able to tell).

For Blu-Ray to Mobile, the MKV remux would be the lossless output.
