Let the hive mind of Engadget get that for you.
"I finally got a new laptop with a lone USB 3.0 port. I'm now looking at getting a USB 3.0 hub with a power adapter so I can use both of my USB 3.0 hard drives at faster speeds. I've read lots of horror stories where some hubs either don't come with power adapters -- and as a consequence the portable drives don't work with them properly -- or they are designed poorly which results in USB 2.0 speeds. Or, the hard drives keep getting disconnected. Do your readers have any suggestions or experience using USB 3.0 hubs? Thanks!"
I have it on both DVD and HD-DVD and the PQ is so-so. The show is supposed to have a rough look to it, so I think they are intentionally making it dull (soft) and drab, then adding some noise to set the mood and tone. Some facial close-ups, CGI space scenes can look amazing, but without a side-by-side comparison it's hard to tell the 2 versions apart and probably not worth the extra money to buy it on Blu-Ray, at least if the season 1 HD version is how seasons 2, 3 and 4 are going to look.
