I think I may have a possible problem with my DVD drive because I do notice a slight creaking sound when inserting the disc in the tray and I have only been successful burning one disc using IMGBURN so far . When I clicked on my computer and checked my DVD-RW drive I'm showing no free space so could this lead to a problem with defaulty discs? I tried updating my drive and don't know if this would help and I continue to have problems with imgburn and would hate to have to find a pay for a application that doesn't work either.
Verify that you have the latest firmware for the drive. Run ImgBurn. Tools > Drive > Check for firmware updates.
Closing this one too pirateboy - stick w/ 1 thread on your burning problem. Leaving this one open - http://forums.afterdawn.com/thread_view.cfm/587928
