Do you own and use a RTV 4000...? Or is this just theory about the RTV 4000?

Entirely theory, I must confess.

I was assuming that the RTV 4000 uses the "Commercial Advance" (tm) technology. If it does indeed use some other way of finding commercial breaks, then all bets are off! I just wasn't aware that there was any other method. Can someone elaborate?
