Video stuttering problem

[steffx]

Hi there,


i have a iDeneb v 1.3 running on my AMD 3400+ CPU (single CPU with SSE3).
I am quite happy, as nearly everything works like it should.
But i still have one big issue which makes a lot of problems.

I can not play video without massive stuttering.
As soon as i start a Quicktime-movie or a movie inside Itunes stuttering starts.
The timeline of Quicktime jumps forwards ans backwards and its impossible to watch the movie.
Same behavier of course inside iMovie.
I also have a DVB-T stick on USB - the live TV over eyeTV runs better but also every 5 seconds i have a gap.
All software is on the actuall releases.

I have a Nvidia-Card with 128MB in the system which seems to do its job quite well on other programs (QE/CI is supported, coverflow etc. runs well) so i do not thinkt this might be the problem.

Does everybody else have this kind of problems ?

Any help ?

thanks
