My dvd & dish receiver run into the 990 then out to my Samsung plasma via svideo (will be via dvi/hdmi Monday). I get OSD on all sources without changing any input on the tv remote.

At one point I also had a coax running (from the out to tv jack) on the dish receiver to one of the antenna inputs on the plasma. In this configuration I did not get the OSD for the dish source,
only the dvd source. I have no idea why.

My thought is the problem lies within a connection or source input at the Samsung. I may have missed it but has he tried running all sources thru the 990 then out? Are there any disadvantages of doing this?
