OK..so I lowered the BAUD rate on the Casa, to see how it would react with the RS232 remote....still working on that.
Tonight...switched from watching TV to a movie. The imput on the Casa should change from imput 3 to imput 1. Which it did. But no picture. At first I thought it was the player...but it was on..and playing. I switched imputs on the Casa...which I have had to do before....still no picture. I had to unplug the HDMI cable from the back of the casa..put it back in..and then I got a picture. So, it has to be the Casa, right? This has happened before. It's not the first time. I usually can just change the imput on the Casa, then go back to the imput I need, and it works..but tonight...it didn't. I had to unplug the cable. Why? Is this still RS232 issues? Does the Casa need to be on a certain imput for the HDMI feed to work correctly?
