Mine is setup like this, TV aerial goes to digibox first then out from there to the video then from the video to the TV. My dvd player is linked by a SCART lead only and when it is switched on overides the TV so you can watch DVDs, while doing this I can record either 1,2,3,4 or 5. The only thing I had to do was tune channel 5 on the video in to the digibox. So if I want to record the digibox I switch it on to whatever I wish and then setup the video to record channel 5. And you're right not even close to being a PC topic.
