So you're wanting to burn these videos? I presume that's the case if you're using TMPEnc. Normally for viewing I'd recommend VLC which has in-built codecs. Pixelation can be due to poor encoding by the person who originally encoded it ... such as using a cheap & nasty poor quality encoder program or codec or they don't know about how to do it well.

For viewing get GSpot to find which codecs you need (though I still recommend VLC for backup purposes if you have viewing problems.)

As for encoding, TMPEnc has had high praises at videohelp.com There are forums which discuss these types of issues. Have a look at CODECs list and alternate players for Movies & also the links at the bottom of the 1st post. Sorry I'm a mac person when it comes to video conversion so most of the programs are totally different (Mac specific brands.)
