I've been having a TERRIBLE problem with channel changing and I have no ideas because it is BOTH of my Tivos, both completely different models ... One a Tivo brand stand alone and the other a Toshiba Tivo/DVD player, AND they are both hooked up to different model Motorola cable boxes (serial cable).
Anybody know what's up? Is it the current software?
It is maddening when it goes to 2 or 3 different channels before it finally lands on the right one and sometimes it doesn't. Then you try to just punch in the right channel number and it doesn't move because it thinks it is on the right one!

So you have to go back to the former channel and hit 'enter' again to go to the channel you were supposed to go to. This has gotten really chronic!
