[QUOTE="htpcoz, post: 28669, member: 13987"] Thanks for the replies... The interesting thing with this is, the problem is specific to the Nvidia Codec, the DNTV live codec I have doesn't have the stuttering issue (although it has other issues with inconsistent handling of the aspect ratio). Also, the interesting point is that the CPU when playing HD channels with the Nvidia codec stays around 30-40%, so I'm never maxing out the CPU. If I have a look at the Nvidia codec properties, it shows all the various codec properties as hardware, not software. I am running 0.20RC1 with the latest CVS patches (although the problem has been the same since back at 0.1.3) I am running the Nvidia PureVideo decoder version 1.02.185 (latest). I do not have an Nvidia video card, it is a Radeon X700, but looking at the Nvidia codec properties I can see that there is no software decoding being performed. But perhaps that is a part of the problem, perhaps the GPU just doesn't have enough grunt to do all the Nvidia processing (although I would have thought that the X700 should have enough, decoding HD material isn't entirely rocket science :) ). Commodore 64, did you find that you had your main CPU maxing out when you had the smothness issues? I'm avoiding the Nvidia hardware at the moment, as I had an Nvidia 6200 card before my Radeon (which replaced a Radeon 9200), and I had no end of stability and performance issues, I'd have to say it was the worst card I've ever owned. knutinh, Interesting thing is that I cannot get the nvidia toolbar icon to display when MP is using the Nvidia Codec. If I use a DVD player program, then the icon displays, and I can access the codec settings. With MP the icon doesn't display and I can only access the settings through graphedit (very painful). I'll check the other forum you provided to see what I can find, thanks for the pointer. [/QUOTE]
