MOV problem

[mowashear]

gents,
Would like your opinion on a certain matter. When i play Mov files (MPEG-4) from my digital camera using FFdshow they appear very jagged (as if the bitrate was lower than the source). As soon as i install the appropriate Quicktime software (in this case Quicktime Alternative), the videos appear ultra smooth.

How can i achieve the same effect while using FFdshow ? The same happens when i convert from MOV to everything. There must be some hidden FFdshow setting which yields the same results as QT, no ?

I have tried Vdub, Megui, avidemux and a plethora of other do it all converters. (Bitrate and quality i max out so i can rule it out) Result is the same.

Thank you
