Is the Pro Logic IIx format significant for use with the 990? I don't see any support for this format in the Denon either. If the Panasonic will end up being as useful as the Denon I'd rather use the jumpers (y-connectors?) with the Panasonic.

I would rather have profile 2.0 but I'm not sure I'd use it for anything other than updates. I'm really not a gamer.

I don't have the technical expertise to know if the Denon is a waste of money or not. I prefer Denon to Panasonic but I don't want to waste my money either. If the Panasonic is more compatible with the 990 then I will go that way.

Thanks again for your help.
