MediaPortal 1.1.0 rc1 has been released. Major changes are the tv-engine TVE2 that is no longer used and that SQL Server has been replaced by Mysql. If don’t want to experiment with the XBMC nightly version MediaPortal might be something for you. MediaPortal has DXVA support out of the box. DXVA support will also be added to XBMC when 10.05 will be released. More info: http://www.team-mediaportal.com/news/global/mediaportal_1.1.0_rc1_released!.html
For who didn’t know: Media Portal is MS Windows ONLY, not linux.
