I have been long searching for a good media center. Since I am still looking for a good one I just use media players such as Microsoft classic media player from k-lite and winamp. But still looking and have tried many but here is the ok list:
XBMC - old version better - testing RC1 - open source http://xbmc.org/
Tried Microsoft Media Center - ok - lastest much better then previous but still slow, buggy
Coming Soon
http://www.gbpvr.com/ - open source
