DO11: No video metadata

Here is what I see.

I think it's only WMV and AVI which are supported in the metadata panel at the moment, but all of WMV, AVI, MP4 and MPG display some metadata in the file display columns.

This is from a vanilla Windows 8.1 (x64) machine with Opus 11 beta 2.

The Enable/fix playback of various media formats in Opus guide may be worth a look if you're seeing different results.
