What is Vr+ Mode, and how can I get out of it?

I have a Philips DVD recorder and a Dish Network DVR. I used to have no problem recording from my DVR to a disc with my DVD recorder 'til one day, just like a virus I started to get this message (ocassionally at first) "cannot record on disc in VR+ Mode". What the hell is this, I suspect it is a "copy-once" protection of some sort. How can I get around it? I feel like my recorder is for nothing now! My recorder is a 3475
