Sansa media converter is there anything better?

are all videos run through Sansa media converter given the dimension of 272x172?    

Is there anyway to make the video quality better? 

I don’t know about the dimensions, but there is an alternative program, video4Fuze.

Rhapsody also converts videos for Fuze.

I know that Video4Fuze is capable of doing a two-pass encode if you wish. This will take twice as long as  the regular encoding process, but the trade-off in quality might be worth it. Just go into the options and check the two-pass box at the bottom of the window.
