If I enable timeshifting, the TV will stutter like crazy everytime I change channel. This goes for both picture and sound.
It is just like the buffer aint big enough, cause if I pause the stream for a second or two then everything runs smooth.
Sometimes the stuttering reappears after a while and I will have to hit "pause" again to be able to watch TV.

I've checked CPU load when zapping and it is about 30%.
Did a little research yesterday and found out that VMR9 is utilizing the GPU to handle the stream. I have no idea how to check GPU load, any one got a tip?

My main question is: Is my videocard able to handle the job?
I got PowerColor Radeon X600 PRO - 128MB (PCI Express)

Sorry for not filling out the support template or posting any logs.
Lets just get the videocard question out of the way first and I will post logs as needed.
It would help if someone tells me wich logs I need to post for this issue.
VMR9.log, Mediaportal.log, Capture.log...??

Have you tried to set the PCILatency of the graphics card to a lower value (often is set to 255, set it to 64 instead)? This only applies to PCI and AGP cards, not PCI-Express.

Hmm, nope I have not tried that. I do not even know what it means ;)

But I found a small guide from Frodo, I will try this when i come home.

My Graphics card is built in (it's a Shuttle ST62k), so i don't know if it will work - but I will definately give it a try!

I have the same problem on my system using a Radeon 9550 card, PCI Latency set to 64.
And when I'm running in no-timeshift mode, after some time the A/V gets out of sync.
Have tried lots of different codecs but it didn't help for any of the problems.

Regards
