Raw dv is just way too big to do anything with. You have the right
idea by reencoding it to another format. May I suggest Flash Video?
I've done this in the past for guest lecturers on campus. Record to
DV, dump to my Mac with dvgrab, then encode to flv using ffmpeg. Then
you can embed the flv file in a webpage and you have web accessible,
flash content that you can easily share. If interested I can give you
the steps to make this happen.
