aber3, I am having the exact same problem. Wont read any disc, whether data, music, or DVD.
I am using a IBM thinkpad, and we tried to reininstall the drivers and everything. Basically my IT department says my DVD Drive is fried, so thanks a lot guys.
Not to mention that I have yet to have this program work to successfully burn PSP files that can be read by my PSP. I have tried at least 4 of your revisions which seem to come out daily. They play shrunk down on my computer, but not in my PSP.
I was so hoping to part with $50 for an all in one solution, but its time i move on. You guys look like you might have a spectacular product here, but right now this is still in early beta (apparantly). I will wait a few months and check back!
