Having captured from a DVD to DV and then pumped it back to DVD  I can 
tell you that this process mashes up the video pretty good.(and can 
mess up your audio too) I am sure that confining this process to the 
digital realm will be better but not much.

And if tapes don't suit you. have them lay these one minute bits on a 
DVD data disc, which can hold a bunch of 1 minute DV clips.
