Hi all,

I don know if this is the correct mailing list to ask, but you never know.

I'm having some problems when playing Xvid files: they stutter.

If I play the same file(s) on a Windows PC with ffdshow and Media
player Classic, they play very smooth with no stutter. So I can assume
the xvid files are ok. I don know if it makes any difference, but this
system is 32-bit.

If I play these file(s) on my myth box, they stutter. I have the
problem with mplayer but also with vlc.

It is not a problem of CPU power. Cpu usage is never above 20 %. The
specs of my system: Pentium 4 3Ghz, 1GB ram, Ati radeon X300. It's
running Debian Unstable x86_64 with mplayer and mythtv from

My system is connected to my TV with a vga2scart cable. So I have
followed the instructions on the wiki:

I'm using the opensource radeon driver. Could the Option
"ForceMinDotClock" "14MHz" cause the stuttering? Or is it the 64-bit

I'm running the system with the irqpoll option otherwise the driver
for my capture card goes nuts. Could this have any influence?

Any help would be very appreciated.
