|I tried to more burning attemps, now with buffers maxed to 512Megs ... one succeeded, one failed. ImgBurn states "I/O error", some more details, and also : "L-EC Uncorrectable Error"|
The disk itself, is an Emtec DVD+R Dual Layer
I had Nero in the past (bundled with some or another burner), but I can't recall more or less failed discs back then (keep in mind, back then the burning was even more challenging), so, that is not a comparison. I do have Nero 5.5, lying around, but it'll not work with DVD's, neither with my Plextor writer.
I like ImgBurn, it has got a very nice interface, but the burning itself is still as bad as with other software. I didn't mention yet, but I have a series of discs (Philips, DVD non-dual layer) which he doesn't want to burn even ... software should accept it, hardware should ...
Burning at lower speed IS an option, but I feel that burning at highest speed is already slow, I'm not prepared to give in on that. I did saw (on the last runs) is that on multiple occasions, the "device buffer" was occasionally at 0%. If I'm right, this is the 8MB buffer.
The "buffer", which I assume is the one I reset to 512MB, stayed at 100% all the time.
