It's worth mentioning that, whichever route you choose (standard USB export, hack with ftp, etc) the transfer is quite slow. Something like 2x real time for HD recordings, faster for SD recordings. Copies which would take seconds or tens of seconds between HDDs on a modern PC take minutes or tens of minutes. You don't have to sit and watch it (though if you're using the standard USB transfer, you can't do anything else on-screen while it's copying), but if you're also going to cut adverts out (VideoRedo Tv Suite) and/or re-encode things, you've got yourself a nice new time consuming hobby.
Cheers,
David.
