Just a quick post to thank Cadboy for this old post.
I just bought a new subwoofer for my HT system and found that the audio was "dropping out" quite regularly when watching DVDs like "The Return of the King", etc.
Per the advice on this board, I "activated" my non-existent 6th channel, and, volia!, no more drop-outs!
I enjoy all of your comments, even on other topics; you guys rock! Thanks for the help!
