I'm no expert on these things but I reckon it would be 300 gigs on usenet too.
actually if you plan on downloading dvd's from usenet then it would much more than 300Gb
The higher up you go the harder it is to tell the good guys from the bad guys.
Is there a problem with downloading all the stuff separately? Being Star Trek, I'd have a hard time believing it's not all available somewhere out there.
