just dumped megabitz. whatever you do, steer clear of these guys as their service has gone to crap. cannon't download a single new HD release without getting about 20% corrupted blocks, and of course there are not enough pars to cover this.
switched to astraweb, and it's a treat. no corrupted blocks, very fast speed - one connection alone maxes out my measly 7Mbps link (US broadband sucks). i can't imagine if i there were decent internet connectivity in my area as 30Mbps via all twenty connections would be sweet. also, retention is better on astraweb - i can actually download files over 100 days old without MASSIVE missing blocks.
$11/month is a great deal. let's hope astraweb withstands the test of time and does not meet megabitz in the abyss.
on a sidenote, if you are going to be downloading HD movies, usenet has been behind lately. a.b.hdtv.x264 is not what it was even 2 months ago. so many new releases are not available there anymore....instead, they are showing up on rapidshare. i'll keep my astraweb account for now as i hope that a.b.hdtv.x264 makes a comeback.
