Mediaportal losing Association with video files (1 Viewer)

[staticx]

Hello

When mediaportal is idle for some time. when I get back and want to play video file, it suddenly cannot find the Association for playing the file, it tells me that encoder not found.
If I restart mediaportal or do a system restart, it works again.

who knows how can I solve this annoying issue?

thanks
