So, I got a new motherboard in my HTPC and seem to be having issues with the USB ports/ MCE IR receiver. It seems that when I wake the computer from sleep, Media Center will freeze for ~ 7-10 seconds when changing channels on my STB. It will put in the first number (so, for 296, it will get the 2 entered) then freeze. I have formatted it a few times, each time trying a mix of the MS drivers and the Asus drivers. I had the same result each time (BTW, board is an Asus M3N78 Pro).
So, I finally broke down and tried the beta Windows 7 I got from MS. Wow. I know its a beta, so there will be bugs, but its awesome for my HTPC.
Just some highlights from an HTPC perspective (aside from the IR receiver now working):
-The new guide (can now display both Cable and Satellite in the guide, with proper updates) No longer trying to find Satellite channels that have similar lineups as your ATSC channels. Also has thumbs for popular programming.
-Supports QAM. Never had a real issue with Vista and my HDHomeRun, but its nice to know that they support it now.
-Can read DVD isos and has its own page like the 'Music' one with thumbs.
-Can find/read many additional audio codecs. It found my I-tunes ripped music and added it to the Library.
-Separate watched folders per Section (aka, your Music folders wont show up in the Pictures Section if you dont want them to).
-Wakes up correctly every time. Yeah, sleep works! And this is without MCE Standby Tool.
I've been using it for a few days and have not run across any bugs that would stop me from using it. The guide can be a little finicky and sometimes deleting/playing recorded freezes the app, but these are few and far between. I cant wait for the release and have a working version of Windows like Vista should have been. I still need to check out which video codecs it supports natively.
