[QUOTE="MichaelMP, post: 388613, member: 89382"] I've installed Mediaportal 1.0 onto a new HTPC (my second one) build with a fresh copy of Win XP Pro SP3. Unfortunately I haven't been able to get any video playback in MP what so ever. I've attempted playback of various video formats using MP's default settings, and also using ffdshow with no luck. TV playback doesn't work (satellite box feed into PVR-250), all I get is an empty dialog box. The error log reads the following - 2009-03-08 11:35:30.968750 [ERROR][MPMain]: VideoPlayer9:exception while creating DShow graph Unable to load DLL 'dshowhelper.dll': This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem.

After re-installing Win XP I still get the same error. My other HTPC runs MP just fine.
