DVD+R for PS2 Backup

[Joules]

AM planning on buying a DVD burner soon (and a PS2 - dont own one just yet!).

Although most ppl recommend a DVD-R, I would prefer a plus, coz I can use the drive like a hard disk. BUT, I have some important questions first!

1. Can I use this disk to read standard DVD-roms, ie the ones I get with magazines etc.

2. Can I use them to burn PS2 games?

3. If my mate has a DVD-R and I have a plus R, are we able to swap data easily?


Im not too worried about DVD-player compatibility, but if the answer is no to any of the above, I may have to go for the Buffalo DVD+- recorder as its the only cheap one that can do both.
Any info on this drive?

Also, FYI I am now living in Japan....although the DVD- disks ARE cheaper than the + ones, the difference is very small.


Thanks for the help in advance! Joules
