sajberman said:hmm maybe the graphic adapter could be a problem, i currently use a Geforce2 card which is not directX9 compatible. There is a ASUS FX 5200 on the way so this might do the trick. but why is everything working perfect with the hauppauge wintv2000 and not in MP? And the recording problems couldnt be the geforce2 problem or what do you think? As for the drivers im using the latest drivers, ive tried both the MCE and non MCE versions without any luck.
I would sugest you test another GFX card if you have one avalable (borov from a frend or something). I allso had some problems with this and as it turned out to be the GFX card that was the problem for me and the symtoms sounds similar (stuttering in MP but not in WinTV 2K).
