Hay, Guys! Extremely appreciated all you warning and recommendation. Yap, use the component switcher recommended by Gonk should be the right and cheapest choice. I will go ahead to get one from Monoprice, to do the switching of 5.1 analogy btw 2 players.
Only the back surround analog inputs at 990 will be used by the blue ray hook-up, not the other player.
Gonk and Scott - then how about when 990 sending 6.1 signals upon PL IIx or DTS Neo:6 or 7-ch stero by the 990 processing. We haven't talk about this if using the component swticher.
Sorry to bother you guys.
