I have the Yamaha DVD-CX1 and its manual says it plays some DVD-R but doesn't mention DVD+R. I want to get a DVD recorder when I get a new computer and I'd like to burn movies that will play on the Yamaha. Dell offer a DVD+R/RW with their PC, but I don't want to get this if I can't burn DVDs that will play on the Yamaha. What's the scoop? Should I just buy a dual format (DVD+/-R) writer and then burn DVD-Rs? Is this the most compatible format for most DVD players?
