Hey Dan,
Yes, probably is like opening a jpg and resaving it, there is a theoretical
loss alwasy is when using mpeg but
in my personal experience DVD-Shrink does an excellent job, you will be
impressed.
Try both ways and see for next time which saves you valuable time.
Because the dvd-shrink is so much faster and re-encoding an already mpeg
file as opposed to encoding the mpeg file originally from an avi.
It can do a 2 hour movie on my system in under 15 minutes, that's fast.
And I am very happy with the results to about 60% recuction, it only will
allow I think 55% or so anyway.
So say 95% is all you would need anyway, hardly noticable. It sounds
backwards, actually only be 5% reduction more.
That's just how they name it in their sliders which can be adj manually or
left on auto to fit a dvd.
You originally wanted a faster way than the all night first time encoding,
an I thought this would help.
Good Luck,
AnthonyR.
