Thanks for the recommendation. I've taken a look at VideoReDo and you
are right. It does do what I asked for with respect to editing - at
least on MPEG. It seems to lack other editing functions which is a
pity. I was expecting a broader range of features. Lossless editing
was just the hardest to find. I'll keep VideoReDo in mind in case I
can't find any other way.
