here is a nice easy solution  go to your homedepot or rad shack and buy
a good 2 way splitter and hook the incoming canle to the input and one
output directly to the hd tv and the other to the dvd/vcrs in. this will
give the tv a much better so-called direct signal and yet  the vcr will
still get is signal for recording. then run the instalation for the auto
search  on the tv , making sure you have cable selected not antenna
that should do the trick
