I am having huge problems with screen pixilation and stuttering on my 64 bit Vista media centre build.

I have an ATI 3850 video card and am using a BGT 3540 Blackgold TV card. Using the DBV-S satellite input.I have Power DVD Ultra and have loaded MPEG2 codec version number 8.2.0.1117. Question 1.

How can I tell if VMC is using this new codec loaded and not the default ones from Microsoft? (I have tried VMCD.exe but it only has the MS decoders showing)

 Question 2.Any advice on what MPEG2 Codec’s are working well for people out there?
