My burner is working fine. I can burn any other content to any format (DVD-R, DVD+R, DVD+RW, actually I don't have any DVD-RWs at the moment). I can burn video to DVD-R as long as it's not the Editdroid ANH disk (although I haven't had a chance to try ESB yet and RotJ hasn't been on MySpleen yet so I don't have it. I can burn data to all formats. I can burn PS2 and XBox backups to DVD-R, DVD+RW and DVD+R. I use Win XP and therefore there are no drivers for DVD burners unless you have Plextor hardware with it's funky Plextools thing, which I don't since I have a Pioneer drive. When I burn a movie, I use the Nero DVD Video mode and copy the required files into the VIDEO_TS directory like you're supposed to. I never, ever include any of the extraneous folders, like Content or Jacket_P since they pretty much do me no good at all and if I want to look at the DVD ROM content I can look at it from my hard drive where it's already residing. So this will be 100% DVD Video compatable.
My DVD burner is working fine. There's nothing wrong with it.
There IS something wrong with the content, which is making Nero think that it's in some way not suitable for burning to DVD-R. Nero lists all the compatable media for this compilation on my burner, and that list is DVD-RW, DVD+R and DVD+RW. Basically everything except DVD-R. I have no idea how or why the content may be unsuitable for burning to DVD-R, but suitable for burning to DVD-RW, DVD+R and DVD+RW. This simply doesn't make any sense.
I will perhaps try to burn this content using a different application. I could try using Alcohol120%, that might not have this weird quirk.
