Sometimes up to 99%. When this happens I get a prebuffering pause and

video kind of glitches. Anybody ever experience something like this? I
have tried changing most of the settings in the setup and didn't see any
improvement. I was thinking about trying another kernel or video card,
but
the video card doesn't seem to be the problem.
Notable differences in systems:
AMD XP2100 proc
Nvidia FX5200
Fedora Core 3
2.6.10 kernel
Hauppauge PVR250
P4 3.2Ghz proc
ATI X300
Fedora Core 4
2.6.14-SMP kernel
Hauppauge PVR250
Thanks for any help you can offer!

If your Nvidia had Nvidia's drivers it would have had hard-decode support,
if
your ATI card uses the xorg drivers it doesn't have that. I can run
800x600
on a 300MHz machine with the right Nvidia drivers, it fails to play
480x480
with the xorg drivers.

Why are you using a SMP kernel? I've never used a Dual Core processor, but
I'm guessing that even then you'd probably be better off with a standard
(optimized) kernel.
I disagree. Its hard for me to imagine any realworld situation
where a smp kernel on a hyperthreaded cpu would not perform at least
as well as a non-smp kernel. And if you have a true dual core cpu,
definately use it. HT may only be a very modest improvement, but
I have 2 machines with 2 Xeon HT cpus, and I set them both up for 4
cpu smp support.
