FWIW I use RW discs and have a similar problem. I have to initialize RW discs in my stand-alone DVD recorder before I can write them with my computer system.
Unfortunately I havent investigated any further, but have concluded that all the hardware which I have ever used with RW discs simply does not work correctly (and all that stuff about getting quality dics is nonsense)..
