Your stuck. My first suggestion is to upgrade to digital cable. That will solve your problem right there. The digital cable box should provide a digital audio output and your standard A/V hookups as well as an S-Video output. Then you would just connect the box to the receiver like any other component and the 1400 does video up-conversion so you would only have to make one S-Video connection to the TV. If for some reason digital cable is not an option you will need to run your cable box through the VCR and use that as your CH 3 tuner. That should answer your question.
