I think your problem is that you have plugged your PSP in, and tried to install drivers, but it could not recognise it. Windows then installs it as an unknown device. You need to remove any unknown devices from Device Manager, unplug the PSP, then install the drivers from the site above. Then plug in your PSP and hey presto, it works!
We have Converted Videp with PSPVideo9 and got it on 1Gb Pro Duo stick and can view and watch this video on our PSP......
We still are having trouble getting an entire DVD on our PSP!
Using Windows 98 with DVD Decrypter and DVD Shrink we can't get 1 file out of an entire DVD.....
We have File Splitting UNCHECKED in poth programs and output image set to .ISO but we never end up with an .ISO image Usually 4 or 5 files with .001 .002 .003 and so on
We RIP main movie only((( No Subtitle, Menu's, or Extra's)))) but we still can't get a SINGLE .ISO image using Shrink or DVD Decrypter...
