I share a cable box between my Tivo series 2 LIFETIME and a Hauppauge recording device. My Hauppauge recordings keep getting ruined because the Tivo is changing channels in the middle of the night, since I don't have a recording set-up on the Tivo. The Tivo records promo junk at 4am, and even though I have "Showcase" turned OFF, I cannot stop the Tivo from changing channels. Tivo support says it's part of the service aggreement to keep costs down. Does anyone know of a way to stop this undesirable practice? I thought when you paid for a Lifetime license, that kind of thing would stop. Guess not.
