Hi guys, I have this twin tuner unit and am after some help or advice. Not sure how to ask so I'll just describe the problem I'm having. There seems to be a long period of time that each tuner is "locked" onto a channel before a programmed recording even begins. If I program a recording to start on one of the turners at say 8.30 on channel 1, while the other turner is already recording, the machine will take me off whatever channel I'm viewing and switch to the channel 1...
