I haven't authored a 2 hour blu-ray yet. So far my stuff has been limited to short subjects. However an AVC encode of a 10min short with an average bit rate of 25mbps and a peak of 39mbps and a standard DD 5.1 track at 448, takes up between 2.5 and 3 gigs. At that rate a 2 hour movie would take up around 30 to 35 gigs. And that is with out lossless audio. It also includes no menus, second audio tracks, logos, FBI warnings or even the necessary structure that is required for a BD to be able to play.
Now a VC-1 encode would be somewhat more efficient, but that gives you a ballpark figure. Of course you could reduce the bitrate, but depending on the material, the image quality may suffer.
