I wouldn't bother I've never noticed any improvement with cables like that - except to the vendors bank balance :) > I am still having choking effetcs and, despite, the improvement that I can now record with audigy2; > I have no idea how to tell mplayer to use the proper device :) > > I tried using adevice but it complained hardly For watching TV I usually tell mplayer not to do the audio (-noaudio IIRC - I'm not at my box) and just set the mixer controls so that I can hear it. For recording TV I use ffmpeg. As for the issue of signals - last I checked mplayer had similar grab code to ffmpeg to catch overdue signals. Try a recording with ffmpeg - if it's much better then something bad has happened to the mplayer grab code. If you get a lot of SLEPT messages on stderr then that will be a sure sign of poor sync detection. > I have a sample video using the following options. Let me > know what you think. In case you wonder about copyright issues. I'll watch it tonight - I'm at work now. The video bitrate seems very low. > It's just part of the "you should buy SKY cable, their informercial > channel" and it's a 10 secs sample... shouldn't be an issue. If I'd be very surprised if that were an issue, but IANAL.
