wow! I just got around to trying that a couple of days ago and it
produces great output: fast, small file size, and no noticeable
difference in quality between the mpeg and the original dv! (I watched
many different clips many times over to make sure!  on TV and on my LCD)

But: the mpeg doesn't seem to scale right.  My laptop display is
1680x1050, and hence the original dv output (4:3) has black edges on
each side, but the converted mpeg plays "stretched", so that everybody
looks fat!

Is this just a _player_ issue, or is it a problem with the encoding of
the mpeg itself?

I noticed the command line has aspect=4/3 in it already, which is the
aspect of the original dv file...

many thanks!
