As in "VHS" ;)

for the better DVDs (part of the remastering process is to denoise
the original material during the transfer to digital).

The other side of that is "removing noise is removing detail". Some
times given a choice between a little noise and softening/blurring
the movie I'd rather have more detail.

Scaling rarely takes more than a few percent of a cpu (but then that's
an Athlon 2800MP ;)) so it's never been a bottleneck that I've seen.
On the other hand scaling has become a relatively infrequent
activity because the data is already at the right size for DVD
creation ;)
