Can't shrink

All of a sudden I can’t shrink my movies. I have been using dvdshrink, clondvd2 and nero recode for a few years with no problems. Now all programs will not finish with ripped movies on the harddrive using anydvd ripper. I was not sure where to post this since none of these programs will work for me now. I have a rip of the new Harry Potter on my drive that I have used clonedvd2 on to make a copy in the past. But it will not finish now either. Help please.

What you mean with will not finish, to rip or shrinking?
Do you get some error messages?

The rip works. All the shrinking programs lock the computer up. No error messages. I have run a mem test that passed. [B]BUT[/B] the cpu test I ran yesterday freezes. I have a cpu or motherboard problem it seems.

Thanks for the reply.

Make sure DMA is on for your drive. You can use Nero Info Tool to find out. Just click on the configuration page.
