Hi, I've been using Mediaportal 1.0.0.0 for a while now but needed to reinstal Vista so I downloaded the latest MP.

I'm having a problem whereby I use WMP HC to play all video in MP and it plays fine, however, when I exit out of media player, mediaportall throws up the message "Unable to Play:videoname" and then lists the video and audio codec. This happens whatever type of video I initially play.

Any ideas what could be going wrong?

Thanks
