Hi - I've got a Humax Series 2 connected to a Motorola DCT 2224/1661/acdegk, and had the IR Blaster attached. I've been through the channel setup through the IR a million times, and it all tests correctly. I usually watch channel 66 on our cable, and record from channel 11 most times. If the TV set is on and I am watching it, TIVO will ask if it can change channels in 1 minute - I usually don't have to answer the question - then it changes the channel at the right time and to the right channel. But if the TV is off, the show I wanted to record is blank (dark screen), the lineup says it's channel 11, but the sound is from channel 66. It never changes the channel when the TV is not on. I've tried to attach the serial cable, but it fails the test - TIVO can't talk to the Motorola serial port. Any ideas ??
