Nero Recode Error


I'm having a problem recoding DVD titles to a Sony psp format in conjunction with Any DVD. It will recode the titles fine, but when it reaches 100% of the total project it just quits responding (NERO) and will not code thumbnails or title of the files properly. Now if I close out the software by ending task it will finally shut down. I manually change titles after this. This only happens when I trandscode "on the fly", it doesn't happen when I rip the title to the hard drive first. And it only happens on multiple title DVD's TV episodes ect. I have done a clean install of both ANY DVD and recode and I still have the same issues. Any ideas?
Thanks for the help & great software!
