Brian,
Do you use the Tosh DVD through component? If so do you have to keep unplugging it to put the PS2 into it?
I couldn't even contemplate pulling my tuner box out to try and get to the back of it, too much hassle fitting it in the cabinet in the first place!! Luckily my little old Dreamcast uses the svideo socket on the front flip down panel, I'll have to sort something out when I eventually switch to an Xbox though!!
I don't even think about screen burn/image retention now, not seen any sign of it at all.
