Just picked up a pack of DVD+R discs on the cheap, and decided to give them a shot in my new powerbook (15" 1.5ghz superdrive). I had read several posts here debating DVD-R discs versus DVD+R discs, since the powerbooks drive is a DVD-R. Well, long story short, I burnt to the DVD+R discs without any problem at all. Furthermore, I also played the burnt disc in a year or two-old Sony DVD player and it worked fine as well. So for anyone with a new powerbook, I can confirm that the 825 drive in the new powerbook will burn to DVD+R just fine. (I was quite surprised with how fast it burnt it too!) I used Toast 6.0 to do the deed, and burnt about 1.5gigs of photos and videos to the disc. I haven't tried it with iDVD yet, but I will. The discs I used were cheapies, I got 25 or 30 for $5 after a rebate at Staples a couple weeks ago. Specifically they are TEON DVD+R 4x.
