I bought a lot of DVD-R some time ago and I just heard that DVD+R is better because you can turn it to DVDROM with booktype thing so it can be more compatible or something. I just noticed on my legit ps2 copies and my ps2 that there is "DVDROM" on them. Now I know you can't booktype DVD-R to DVDROM so I was wondering, since I am still a newbie, if I made a mistake of buying those instead of DVD+R? Since I did 25 backups with DVD-R with no coasters (and they weren't TY!) I just want to be sure that I did the right purchase. Thank you.
