I have 1.03 fw and have not had any issues as of yet. I got my drive at Best Buy, while returning my liteon 411s that I had numerous problems, (not bashing) I had already made up my mind on a Pioneer, (have the dvr-104) There were no Pioneer's on the shelf and when I went to ask , there were some in a basket, not put out yet. I asked if I could buy one of these, thinking it was a dvr-106, the clerk said "sure" At the counter I noticed it was in fact a dvr-a07. This was in the middle of January, I have not seen one in a store since. I am a little embarrased by what I paid, but I just wanted to quit messing around, and not worry about media, and compatibility. This drive has been rock solid, with no problems whatsoever.
