I have a Pioneer 110 flashed to 1.39.
Recently I have been burning some Datawrite Titanium 8x DVD-R's (MMC 02 Dye) but every now and again it'll create a coaster. Well actually a few. The weird thing is that its not just one or two coasters. It'll burn like 3 in a row and then burn fine and then start creating coasters again. I know I created a post for this about a month or so ago but couldn't find it.
However since I last posted and I was told they were crap disc's It's started happening with my Datawrite Titanium 16x DVD-R's (MMC 03 Dye) and Arita DVD-R's (Ritek G05 Dye).
I never had any problems before with writing DVD-R's on my previous NEC drive.
Do you still think they are crap disc's or possibly a problem with the writer?
Would a firmware update to an unnoficial version help?
