How does a tivo change channels?

Archived from groups: alt.video.ptv.tivo (More info?)

Hi, all. This is the one thing that's really preplexing me. How does a
tivo go about changing channels if you tell it to record something on
channel a then channel b? Does it use something like the IR Blaster (or
are they using the IR Blaster itself)? Also, I'm wondering how reliably
that works. I talked to my cable provider (Cox communications, I'm out in
Tucson, Az) and had a rep say IR Blasters don't work with the newer boxes,
but that just seems silly (I mean, if you can program them to work with a
Universal Remote...). Although I can imagine cox sabbotaging whatever
tivo's use to change channels, thereby making their PVR that much more
desirable... Anyway, TIA .

I use the supplied serial cable with a Motorola DCT2000 cable box. Works
awesome. Never had a channel "misfire". Also depends if the cable company
disables the serial port on its boxes. Luckily mine doesn't.
