I do actually have an add on USB3 card. Unfortunately only one of my USB3 HDDs works with it.

The GPU's pretty bad, but I don't really play games, so it's not that much of a problem. 3D effects in After Effects are pretty slow but I don't use those much either.

As to the menu, I was actually thinking about MultiAVHCD but I'm not sure what its capabilities are or how complicated it is. I do have Adobe Encore, that came with Premiere CS5.5 but I can't quite seem to figure it out.

Another question, I found out that dts-hd doesn't play on my system, neither as a separate file, nor muxed in with a movie. Why could this be?
