What feature about gpu3 is not present with gpu2? I presented the fact that Fermi cards require more cpu resources but this idea was dismissed.In other words,what is it about the fact that you see the problem with gpu3 folding that is unique and causing the problem that you see?

I don't know the difference if any between GPU2 and GPU3 but "Fermi cards require more CPU resources" was dismissed as the reason because first off this same problem occurs on my GTX 260 c216, and secondly the CPU folding has no effect on the problem, only GPU folding. If my 2500k is sitting idle but netflix is stuttering because the GPU is folding then that doesn't really look like a CPU issue now does it?

Who mentioned cpu folding (other than you)? It is true that Fermi cards require more cpu resources (some people dedicate an entire core to a Fermi card). I brought this up as the OP is using a dual core cpu and if one is used for folding that leaves one for Netflix and Netflix will show stuttering on a single core.

It's just not a CPU power or usage issue. It's GPU related, all evidence points toward GPU.

Netflixs will run fine on onboard video. The OP has a 465,surely this is equal to the lowly ATI 3300 onboard video on my ASUS M4A78T-E. It is when cpu usage hits above 65% (this is a Netflix figure) that stuttering can start.I know our OP claims 16% cpu usage but I want this figure verified and a call to Netflix can give you what their equipment says your cpu usage is.I can run so many combinations of equipment (and folding on that equipment also) and no stuttering.e5200 and a folding 8800GT no stuttering.I mention the low gpu requirement of Netflix simply to say,yes this is a gpu problem,a gpu that is hurt by high cpu usage.

EDIT: I wanted to add that it is suprising that 16% cpu usage will even run the gpu when the gpu is folding and we are being told that it is 16% while folding and running the streaming video. This is a figure that strikes me as unreasonably low.

Running prime blend right now (so CPU is @ 100%) without GPU folding and no stuttering in netflix, stuttering starts immediately when starting folding on the GPU, stopping prime on the CPU but continuing GPU folding has no effect on the stuttering. The only thing that has had any effect on the stuttering from my multiple tests, using multiple methods on machines of varying levels of performance, is GPU load.

I was running a single core cpu on an old Dell 4300s and had the stuttering problem. I gave Netflix a call and this is when they said they see my cpu usage up close to 95%,this is when they told me that it can start happening at 65%. What I conclude there is more than one cause of stuttering so each fix is going to be different.

What we can say is that this is the only OCN folding partner that is complaining about this level or perhaps better said this difficult to identify a cause for streaming video stuttering.Logic tells me the answer is going to be something unique to the OP's situation. What I initally identified as unique to the OP's situation was such a low powered cpu with a Fermi card.I ask is this combination the source of the trouble or is it a priority issue.It seems that the OP has been all over the priority changes and it is time to say that this combination of components (I still do not understand the inclusion of Media Center) is the cause of the problem.

No he's certainly not the only one this happens too, it happens to me on multiple machines and I've heard of others it happens to as well. How about this can you fold on the GPU while watching netflix?

Juano,yes I can gpu fold on any of my dual core or better and gpu2 equipped machines while watching Netflix without issue.I do not have a Fermi card to test with but no stuttering issues what so ever with any of my 8600,8800,9600,9800,275 gpus while folding.

EDIT: Perhaps it is time I get one of these lower Fermi cards and make some tests.

EDIT: I think I see something we all have been overlooking,the OP is not operating a "normal" monitor. This 42 inch display may be the issue that is the component that is out bounds in regards to what I am familar with.I have been commenting all along as if this was a normal computer monitor.I think a computer display should be "stubbed in" and results noted.

Elo: Zodac did mention drivers a few pages back but I really think I am on to something when I say this is related to using a TV as the display device.I do not feel that 1080p is really being delivered (I read that the display defaults to a lower resolution for Netflix).That being said I don't think the problem would be related to 1080p even if it was the actual resolution achieved.

I don't know if anyone has mentioned this (I just skimmed the thread) but you might get better performance out of a different driver. I get much better performance for folding/watching video out of 260.99 drivers than any 27x (or even the 280 beta drivers). Also, I don't get the 2d clock problem out of the 260.99 drivers. -could be worth a try.
