As I said, Nero was happy to burn to DVD+R, but not DVD-R for some reason. I tried removing everything except the VIDEO_TS directory and still no dice. Like I say, it'll burn to DVD+R but Nero simply says it's not suitable for burning to DVD-R.

I've never seen this before in a couple of years doing stuff with DVD video.

I rarely bother to burn the Jacket_P and Content folders as they don't really do me much good and might confuse some older players.

As I say, it's not the end of the world since Editdroid isn't anamorphic and therefore isn't much use to me except as part os a collection.
