Ben Drawbaugh got the leaked copy of the RTM build of Windows Media Center TV Pack and posted his hands on installation experience over at EngadgetHD.
We have to say this is a pretty nice upgrade, but most definitely not everything we wish it was. Beyond the obvious missing H.264 and DirecTV support, there are plenty of things we wish were included like: 16x9 thumbnails; ability to list Recorded TV by date and put it them in a folder; and the ability to filter keyword recordings by HD -- you can however now set series recordings to HD only -- just to name a few. The update isn't all good either, as we still haven't figured out which plug-ins are compatible and so far we haven't found anything that can play the new WTV file format -- yes we tried VLC. But as soon as we find a way to play back the files on another computer, we'll be sure to check and see if the new more lenient CableCARD DRM is in effect.
