Clonedvd 2 question

[spoonb4u]

I have used clonedvd 2 for awhile now to backup my dvd's. Today I ran into a problem, when I clicked go, it said I didn't have enough space 4.38 gig required and I had 2.59. I've never needed to do that before! Also how can I move my video_TS file? Or can I create a new one? Or do I uninstall and reinstall?
I am using winxp, 2 gig virtual and have 1.96 gig remaining memory.
Celeron processor, i/o magic dvd burner. Never had any probs before. Oh yeah Ridata disks.
I always burn on the fly so it doesn't have to be saved to the hard drive, its just automatically deleted when finished.
Thanks,
BK
