I mean, I can't stand the judder at all.. I think that's why I went away from watching my ripped content until recently when I went out and got a separate video card for my first htpc (original i3 cpu)... the playback just sucked. It's so distracting to me.
So, is the issue that some people just don't notice it, or is it similar to the audio arguements (alll amps sound the same, etc.)? Because if it's the later, I'm willing to take a bet with anyone that I can tell when it's happening.
Anyway, I went with a frield's recommendation and used an AMD this time around and it's much better.
