And now, after several days of clean Windows installation and with v. 1.0.1.2 driver, I notice that there are still small sound clicks present (like when video and audio goes slightly out of sync and software or hardware re-syncs them with the video stream in higher priority). Also sometimes I observe quick corruption of parts of the frame.
Will observe 1.0.1.2 for one day more and then will try that old custom 1.0.0.2 I attached to one of my replies in this thread.
