Ripping umds

I'm having a problem ripping an old game of mine (dynasty warriors). I was able to copy it but for some reason it has the same file numbers as my burnout legends game. Also when I play the dynasty iso it ends up plying my burnout iso instead. Tried renaming it, didnt work. Any suggestions?

You used the VSH menu to switch the usb to the UMD drive right? Try just writing it to a different location on your computer and renaming it there before copying it to your PSP. I have no idea if it will work though, I've never tried to put more than one ISO on my PSP.

did that already several times Just forgot to put in my post. i've been at it for four hours now.
