Does it work with DD-5.1 / AC3?

DRM issues aside, the problem with WTV is its bloated size.  In my experience, for any given recording a wtv file is over 40% larger than a dvr-ms file.  That means my hard drive holds just 60% of what it did before TVP 2008.

Is it confirmed that Zune still won't sync with TV Pack CableCard pc's?

Hopefully someone who works on Movie Maker gets this documentation!!  I read on MS forums that the Media Center team is responsible for making .WTV a recognizable format.  The forum I read had some MS employees acting like they couldn't touch it with a ten foot poll and that we should keep our fingers crossed!  I was pretty shocked that this is that type of situation.  Am I wrong to think this shouldn't be a big deal and that a Movie Maker update could've been slipped in with all those updates a week ago or so?  Not to mention the need for .WTV support on non-TV Pack machines....Q
