Hi

My set-up involves a Sony DVR HX715, a Sony Trinitron, and a digital
cable box (not HD). I

1. The DVR is connected through its Line 1 Video/Audio output to the
Cable Box.
2. The DVR is connected through its Line 3 Video/Audio output to the
television, with the exception of the video jack. For this, I'm
running an S-cable between the DVR and the TV.

The DVR comes with a Set Box control, which allows one to control the
cable box through the DVR's remote control. I got this to work.

So when I move through the DVR and TV's input's, the outcome is
basically the following ("WORKS" means the channel tuned through
the box comes in):


DVR TV
Video 1 Video 3
L2 Nothing WORKS
L3 Nothing WORKS
DV Nothing WORKS
L1 WORKS WORKS

What I can't figure out is how to separate the channels, i.e., to
record one channel while watching another, which the guide says can be
done. If I tune the Box through the DVR, and then change the channel
through the box (so that the numbers are different), the DVR recognizes
the number on the box and records that channel, overriding whatever I
had chosen (through L3). Then, if I go through the inputs on the DVR,
when it gets to L3, it changes the box's number to that displayed on
the DVR, and the channels get coordinated.

The bottom line is that I'd like to know how to "split" the
tuning of the channels, so to speak.
