Advertisements I just installed a PTVupgrade drive in my Pioneer DVR-810H. The drive seems to be working fine., However, I can not set it up to change the channel on my digital cable box. During the guided setup I get to a page where it instructs me to choose the brand name of my cable box from a list below. However, there is no list. There are no brand names and there is nothing to choose from. I backed out of and skipped that step. The trouble shooting tips from Tivo Central instruct me to set this up at Message and Settings > Settings > Channels > Changing Channel. However, the last menu is not listed on my Tivo. I do not have a 'Channel Changing' menu. My guess is that the software is inomplete or corrupted. Is there any way I can verify this and/or get the complete software. My Tivo is dead in the water if it can't change the channels on my digital cable box using the IR.
