DVD to PSP help

Hi all, I’ve been trying for a couple of days now to transfer a DVD to my PSP. I pretty sure I’ve covered all suggestions in this forum, and I still can’t get my files to play.
I’ve renamed it, put it into the folder directly through DVDFab and by copying it, I’ve tried ripping it in the 2 different formats… and it just says ‘corrupted file’ or ‘Unsupported Data’.
Has anyone got any ideas?

I have been successful with using anydvd along with clonedvdmobile. Go to www.slysoft.com and you can download a free trial version that will work for 21 days. Good luck
