I can't see anything obvious in your logs. I am downloading ep 267 now, to see if I have any problems with it.
In the mean time can you check your version of MediaInfo.dll.
You may need to download a new version
MediaInfo - Download
I just downloaded the newest version (0.7.29.0) of mediainfo. I dropped it in "C:\Program Files\Team MediaPortal\MediaPortal" and "C:\Program Files\Team MediaPortal\MediaPortal\plugins\Windows". It doesn't seem to have made a difference. I shouldn't have to register the dll, right?
