Sony RDRGX315 DVD Recorder
Switching
The Sony RDRGX315 DVD Recorder needs to be hooked up to a cable/sat box to operate.  I have cable but no box.  Without the box, you cannot view the DVDs nor can you switch from TV to DVD.  Very bad design flaw.  If you purchase one, look at page 12 for install notes.  I returned it. <br />
