<p>Good day hope you can help me. avi and wmv video works fine, but when I tried to play an mp4 video I get the following error message. The operation cannot be performed because the pins are not connected ($80040209). What does the following error mean? On Windows 7 64 bit, using Openlp in compatibility moide. Installed bot CCCP codec and K-Lite. File works perfectly in Windows Media Player 11.</p>
<p>What am I doing wrong?</p>
<p>Answer on web, is a difficult Windows bug to fix. Nothing to do with OpenLP</p>
