I made images of some unlabeled discs I had around, two of them were tha same sector for sector, but for some odd reason one had junk at tha end (to pad sector, not sure, but seen this before, didnt look into it yet) and slighty bigger file.. Now, when I compare tha smaller dvd against tha bigger image file, I get sucess on tha verify.. But when I compare tha bigger dvd against tha smaller image, imgburn just hangs at 99% with no error reported.. Thanx..
