Fishnose, I'll believe that. :) But, I've not had any success writing, let's say, 4.3GB (real GB) without the software complaining. Do you have the Sony DRU-500(A/AX/?)? They are nice aren't they? I'll tell you this, though. I can write K-hypermedia DVD-Rs on the Sony, but can't read them on the Sony. Read okay on other drives, but not the one that wrote it. So, I use better quality ones instead of that coaster-fodder. :) And, yes, I check my DVD archive after write against the data on hard disk for file count, directory count, and total bytes to ensure that everything was written properly.
