I recently installed Comcast's digital set-top box to my HDTV (in order to get HD channels). However, my VCR's timer programming no longer works (currently the cable goes from wall to set-top box to VCR to TV by the way). It must have something to do with TV's channel being fixed on channel 3 now, and channel switching being controlled by the set-top box (so the timer programming only works if the preset program is on channel 3). Any idea how to continue to use the full feature of a VCR with the existence of the digital converter/set-top box? Use cable splitter, switch, and/or ??? I don't suppose it has something to do with my VCR not having a digital turner??
