The ones I heard with issues are from the XP boxes. Unfortunately I don't have MCE to compare. I might look into this. So what version should I only be updating to for MCE? What is the build of MCE? I definitely want to step up to Purevideo and see if PQ is much higher. I know when I first tried it a while back trial version Purevideo DVD player was working properly but Window Media Player 10 would not play any DVD's. This was during its first week of launch so I just reverted back to NVDVD 2.5 and did not look into it again.
