I have the same issues. It appears to affect Live
-Tv broadcast's viewed and recorded/playback
through Media Centre and WMP.
As a side note i installed Media PLayer Classic and discovered that this has no issues with viedo qaulity. I have also updated all my DirectX compenants. I am not using any additonal codecs (aside from those installed with Power DVD 9 Ultra). My Windows 7 is brand new with no other programs installed.
There is very bad artifacting in HD Videos displayed. On this same machine with the same hardware using Vista Ultimate x64 (dual boot), i had no artifacting.
I've checked my video card drivers
, powerdvd settings etc. Nothing stops the artifacts.
Is there anyway to adjust video settings for uncompressed video formats like dvr-ms in Windows 7?
