Still can't get the extra tracks to play in 5.1???
Edit finally got it but there seems to be a flaw in this DVD. I have to really work at it to get it to work.
First thing I did when I got the disc was suck all the bits into the computer so I could play everything back via the Squeezebox. Maybe there's some authoring issue that makes menu navigation unreliable, but there was no issue extracting the extra tracks to a hard drive.
