Yeah, simple.

Stop watching it in Media 'Player'.

Get the free version of Quicktime and all that crap will dissapear. It's just the way Maya encodes AVIs - nothing to do with the way it renders them.

But if you really wanna keep using that player, just re-encode the flie before viewing - though that'd be the undesireable option since the vid would have been compressed twice then.

Best method is to output single frames from batch render then stick them together with whatever software takes your fancy.

EDIT: Just make sure you use a lossless compression format for the single frames though - jpg just aint going to cut it. TGAs are a good option, btw.
