Random blocks of color appear on xvid/avi movies on mini player

When playing any XVID movies, I get random bolcks of color appearing for a few seconds.  This happens 2 or 3 times during the movie.   I thought it was the player so returned it.  The new player does the same thing, plus it won’t let me move files around - my  previous player would.

Have you tried playing the file on a computer?

Same result?

Usually these color things are compression issues from the creation of the file.

Have a try with VLC ( www.videolan.org/ vlc/) and see if the colors appear there as well.

I have the same problem with every Xvid I play.  I did chcek it on VLC player, and two others and no problems.  I have a philips media player which does not have the same problem.  Any other thoughts?  Is there a encoder that works better than others?  Or perhaps settings that work better.
