LO, Sorry I didn't check the site this weekend, but I had the same problem when I used a DVD player with 5.1 inputs for a little while. Exactly as Cadboy mentioned, if you go from an input with nothing connected (i.e. video 3, aux or something like that), there is no bleed through. It actually happens with any source that is active before the switch to 5.1 analog.

I just verified it again, just to be sure, but as Cadboy said, use a dead input prior to switching to 5.1 analog and all is well.
