It's obvious that we have several things in play here; (1) A new hardware device from Asus, (2) A retail version of TMT, (3) A separate or branched code path of TMT that is being developed specifically to work with the HDAV, and (4) a new driver set from Asus that will allow the HDAV to talk to TMT in the first place.
Normally we as customers would expect all of the above elements to be properly put together behind the scenes with the final product shipped completely ready to go. Obviously this isn't happening with this product nor do I get the sense that Asus is effectively working with Arcsoft. I can't believe that ASUS allowed this product to ship in any country without any of the above loose ends tied together. I agree that Vista drivers needed to be a release requirement. If they wanted to have a beta program than they should have identified key testers (like us) and shipped some eval hardware way in advance of releasing anything to the general public. I would have expected that the two code paths of TMT would have been merged with a single release version coinciding with the launch of the HDAV so both HDAV customers and regular TMT users would be on the same version. What we have now is all sorts of versions and patches floating around both on the Asus and Arcsoft web sites (unofficial pre-release patches are even being published on the Arcsoft message board by someone that works at Arcsoft but admits he isn't part of the HDAV team or even has access to those folks). I consider myself an expert in this sort of stuff and I frankly can't figure out which version of what would need to be tested even if I lived outside of the US and had a retail HDAV in hand.
Asus has never impressed me at any level unfortunately. The web site is clunky at best, telephone support is abysmal at best, and their message boards have also been sub standard the few times I needed them. I am not surprised they have effectively botched this release. Even with all of that being said I will be one of the first to purchase both the HDAV and their upcoming custom 4870 X2 TOP card once released in the US. They seem to make good hardware but simply fail at these other points I have been highlighting.
