Sorry I disappeared for awhile - RL got me. I'm only using the TV's speakers, but I think I found the right button to push - there's a toggle button between 5.1 & 2.1 on the remote. As far as I know, I only have 2 rather than 2.1, but I can listen to movie dvd's now. There doesn't seem to be a setting for TV Sound Only unless it's the 2.1.
By tracks [probably the wrong term] I meant that I could hear some of the conversation and sounds and not others. It was like a half-mute.
I also discovered I have to go into the menu setup and set video to YUV if I don't want everything in pink. [component cables]. I keep reading the little manual, but the print is small and a lot of the terms unfamiliar.
