If it were possible for TiVo to implement caller ID, I would disable it even though I desire that feature. AFAIK the modem in the TiVo boxes sucks. Having the Tivo in the "Auto detect line status" mode keeps the modem on and this causes problems as is. It's something with the firmware crashing and increasing the susceptibility to electrical disturbances.

I assume if the modem were listening to caller ID all the time the same issue would arise. All I need is the $5 modem on my $400 + $199 lifetime sub DirecTiVo. Not.
