no we don't. as there's no HD/blue ray burners we can buy yet & they normally cupport a tech after, not before (IE 64-bit) it comes out I doubt it will right out of the box.
an update may though, like V4 supported HD with the "b" update.
Nothing wrong with asking, but I can be 99.9% sure that, unless Sony does an about-face on their current practice, it's not gonna happen. They're pretty strict about (at least trying to) keep DVDA in line with the official DVD specifications.
This is why, I'm guessing, DVDA doesn't do mini-DVDs, VCDs & SVCDs, PAL and NTSC on the same disc, DVDs with MPEG1, DVDs with MPEG2, or DVDs with non-standard resolutions. Also doesn't do DVDs with MPEG audio, but that's actually a bit unfair to those in PAL countries 'cause it's fairly standard there.
Of course, if "mini-HD-DVDs" become part of the HD-DVD (or whatever it's being called) specs, then that may be a different matter.
My guess is that the software allows you to construct menus that WM player understands. - I got a demo DVD from microsoft that has some sample scripts for menus - very interactive and very impressive, but as its a scripting language kinda time consuming to build menus.
I'll contact them to see if I can get a sample disc (address at the bottom of the page), though the last time I tried watching an HD WMV, my system wasn't quite up to the task.
