Ah, so my guessing was quite not too far off then. >You can reduce any problems a lot by pausing the movie while you do >the switch, giving it some time to get its act together before >playing it again, Unfortunatley it's not an option in this case. > or/and you could make the key frames more frequent.

I could use any codec but I guess Sorensson is still adequate if I use more frequent keyframes. Thanks for the help! -A.
