From most any other common source a VHS tape will
contain material that only requires "Cut & Join", which
can be done totally without loss at the "I-Frame" ( no
re-encoding) or with "Frame accurate" cuts ( only the
effected GOP is re-encoded)
There are many here, in this NG, that make use of
Editing procedures that can't be properly accomplished
while in a lossy format like MPEG. Those in that
situation know that fact, very well. They would not
have made the post we are responding to.

There, isn't it better with the rest of my post, instead of
having just a part, out of context? Or didn't you understand
the implications of the rest, especially my last paragraph?
If I were working from digital camera footage, I would agree
with your paragraph above, for that process. But when capturing
a commercially edited video program/movie from a VHS tape to
be made into a DVD; I'll capture to DVD Compliant MPEG. This
means that all that I have to do is cut out any unwanted parts and
Author the DVD. I'll have an "edited" and authored DVD, in my
hand, within 25min. after the capture. It will never have been
re-encoded and, at any decent bitrate, will be indistinguishable
from what you see playing the tape. (in most cases it will be cleaner
and sharper)
If I were bound to your approach only, then I'd have to:
Capture in real-time to a "lossless" format (Huffy?), then:
Demux to elemental streams, then
Process the Audio, then:
Edit the Video, then:
Remux and Encode to DVD Compliant MPEG, (for ? hours
per hour of the original video) then:
Finally - Author the DVD.
And the sad thing is; there would be little if any noticeable
difference in the result.
Luck;
