I tried recording a TV program the other day using ATi AIW 32MB DDR Radeon (Multimedia Center 7.1). When I played back that program, the video was OK, but there was no audio. The audio was fine while I was watching the same program live (while the recording was in progress); I made sure that there was no "muting" anywhere in the play control panel. My setup: P4 1.4 512RAM WinMe; sound:SBAudigy (line out from AIW to line in in Audigy; optical audio out from Audigy drive to receiver); Powerstrip, nothing else extraneous. Any thoughts as to what I might have done wrong? Many thanks in advance.
