Slow mo or jerky on some vids ?

[billanben]

Hi all

Maybe you can help. I am probably missing something obvios but can anyone explaon and/or give solution to why this happens.

I play a downloaded file (maybe avi) on either MPC or ZOOM Player and it plays back in slower motion than I would expect but is smooth. If I play same file in VLC player, it plays normal speed but is VERY jerky (stops for periods, then plays again). Is there some settings changes to make or is it just the way the vid is and have to live with that ?

Thanx
