UPDATE 3:
Ive removed old ImgBurn, deleted "HKEY_CURRENT_USER\Software\ImgBurn", installed new 2.5.0.0, started it, didn't change anything in options, switched to "Mode - Write", selected 1st DVDRW by default, put DVD in DVDRW, ImgBurn loaded status for DVD in right window:

and when I try to open it in Windows Explorer/Total Commander/load image from DVD with ImgBurn/anything else, I cant, I'm getting error:
"Please insert a disk into drive M:" or
"Drive not found! Please choose another: [-m-]" etc..
When I switch in ImgBurn to another DVDRW, than I can open drive. After I switch ImgBurn to M: drive again, I can again access M: disc. When I put another new discs, I can again open it (even if ImgBurn is still set to M: drive). But, after I burn ANYTHING again with ImgBurn, I cant access any DVD (until I repeat this process with switch ImgBurn to other device, load disc, and than again switch back to 1st device).
Its the same on 3 different PC's (Asrock, Asus, GigaByte MB). ATA and SATA DVDRW's (Liteon's and Pioneer's).
I really don't understand why does this happens if you say that it shouldn't.
What is interesting that when I start Nero and do copy/copy DVD (and the drive is locked by ImgBurn, in this case M:) Nero freezes 5-10 seconds and then start to burn DVD (copy (read) from this M: drive). The drive is locked by ImgBurn, but Nero manage to unblock it after 5-10 seconds (Nero usually when ImgBurn is turned off starts to read and burn immediately).
I burn a lot (I have 4 SATA DVDRW's on ASUS PC) and ImgBurn is my favorite burning software (just that it could do copy/copy DVD's), but this "feature" is little annoying .
