yes, they are full.
I havent tried doing test burns or burning at higher speeds, but ill try those and get back to you.
i have another question though, about something else. Just now i tried burning an iso with lots of stuff running in the background and my buffers were going up and down (normally they stay full until the burning is finished). I was wondering if this is bad at all for the image. Like, would i get the same quality disc if i burned it like this, than if the buffers were full the whole time? (might be a stupid question but i dont know what the buffers do :S) Heres what part of the log looks like:
