I had the same problem for several months with my VAIO laptop running Vista. I even called Sling Tech Support, but they couldn't fix the problem. I searched these forums and google for the answer, but only found questions like yours. I was ready to install OS X on this thing in an attempt to fix this. Well, I just found out what the problem was for me, and I'm ecstatic about it. The issue was qttask.exe, the QuickTime taskbar process. It was preventing Vista from running the AERO desktop (whatever that means), and preventing Slingplayer from using VMR. I found that for me VMR was sufficient to improve the pixelation dramatically, and I couldn't tell much if any improvement with VMR9.
So, check to see if you have QuickTime installed and if so, disable the taskbar process from loading.
Sure hope that works for everyone having the same issue, and I think Sling Tech Support needs to know about this, as well.
