Yes, I am seeing exactly the same thing. I have a PVR 250, a Radeon 8500
in a AU13 mobo with an xp2100+. I recorded Terminator 3 the other night.
The intro/credits is very dark, and the audio cut in and out during the
playback but the rest of the movie was fine. I also see sporadic
artifacts during live Tv watching. I am new to Myth and still
configuring stuff so had assumed it was my setup, but maybe not.
Too bad some one hijacked this thread for another topic (which became a
flame war) because I have no doubt nobody is still reading this thread...
