I have a TiVo HD hooked up to a Cox tuning adapter. I have a Season Pass for the New Outer Limits on Chiller. The TiVo is usually on standby when I'm not home. 1) If I have no tuners tuned to Chiller, about half the time the channel change will end up with no signal, causing no recording to be made. If I were there, a channel up/down two-step usually causes Chiller to give a signal. 2) If I have a tuner tuned to Chiller, about 1/4 of the time either the signal will be lost before the recording starts, causing no recording to be made, or it will be lost in the middle, causing the recording to be truncated. What's causing this signal loss? Is the TA just dropping the channel without asking the TiVo if it's still interested? Is the TiVo not responding to the TA? Is there any way to stop this from happening?
