Wow.  That's pretty amazing.  So it's at least cheaper to use external 
HDDs than the original tapes.  (I paid $5/tape, I think, which is almost 
twice what I would pay for the same volume in external HDD).  I'm 
disappointed that there isn't better lossless compression.  I haven't seen 
the 1TB for less than $250, but I believe you.

Interesting.  I've been using Pinnacle Studio 9 to get the video from the 
tapes (via firewire to the camera).  I didn't realize that there was 
another format that could have been used.  Pinnacle Studio uses the AVI 
format but maybe there were other choices.
