I have a Mitsubishi 50801 RPTV which is about 3 years old. On the back it has two sets of inputs, each having S-Video, composite and stereo R/L. I have my Yamaha receiver connected to it, with the S-Video in input 1, composite in input 2. I could have sworn in the past that if I tried to connect both lines from the Yammy to one input, only the composite would be visible. This was happening because regardless of what input was selected, the Yamaha was sending a signal down the both lines and the Mits was choosing the composite over the S-Video. However tonight I tried it and the opposite was happening. It was favoring S-Video over composite. This is great because now I can hook my DVD directly to the TV by sharing input 2. What bothers me is that I'm sure the opposite was happening in the past, or else I would have hooked my DVD up directly already. Last fall I had to have some work on the TV done. Something was wigging out on it and blue was sometimes green. It was quite annoying. The guy replaced several parts, the first ones in error, and finally got it working. I'm wondering if this changed how the inputs were chosen. I've also upgraded from a Yamaha DSP-A3090 to the RX-V1 since the last time I fiddled with this. But I don't think that would change anything. Does anybody out there have this model or a similar one that could tell me how theirs chooses inputs?
