I've tried
CloneDVD and I must say the quality is poor.
You see a lot of blocks and artefacts in the copy.
When I copy a DVD5 to an other DVD5 were only the subtitles were removed (no compression) the quality is as bad as a copy from a DVD9 to a (compressed) DVD5.
I think you can better use
DVD Shrink to make your copies.
Its for free, so don't pay money for software thats not better than the freeware.
