Hi lloyd1e, first point is don't start a new question but continue with the old one, then people will follow the whole sequence of your problem -
If the set top is now connected to the vcr via the bnc plugs marked video and sound this is the line input and NOT a channel, the vcr must be set to use the line input and not a channel, most vcr remotes have a button marked I.Select or Input select or something like that which cycles between ''line in'' and ''channel in'' with each press and the display will show a channel number ot LI.
