So, A guy gave me a 43" Hitachi RPTV. I changed out the convergence chips and it works fine. My issue is that the factory remote has individual buttons to move through the inputs ( 1 through 5) and has a single button to move between A and B (antenna inputs (75 ohm coax). I tried every Hitachi code for my TiVo remote and the only ones that worked would only switch the ant inputs and I would like the TiVo remote to switch the inputs (1 through 5). Has anyone been able to get this result with a TiVo remote? I don't want to switch my TiVo input to coax for the (albeit nominal) quality loss.
