I also will second or third the comments about the new feature transcoding and syncing Media Center TV shows to the Zune within the Zune software. Specifically, I am interested in:
Does it handle both analog and HD dvr-ms files equally well?
How long does it take to convert and then sync a 1 hour TV show? How much longer does it take for HD dvr-ms files?
How much does to reduce the size of the file for the Zune?
Does it sync all Media Center TV shows or is there a way to filter what to sync?
Also, does it cache the converted file for other Zunes or does it have convert each file each time for each Zune?
(The last two questions may seen a little odd, but my wife and I each have a Zune. Our TV show tastes contain some in common and some that are unique.)
