I have 625 and on my second tv, (which is actually my main tv) when I press the tv/video button it doesn't change my tv inputs. I've tried while under SAT, TV, and VCR but none of them work. It's the only thing that won't work for my tv so I don't want to use the tv remote just for one thing. Should I try a different code? Also, if this makes a difference, I have a Toshiba tv.
