Wrong frame rate information in case of interlaced content
In the GUI, Codec Information: in the case of interlaced content, the "frame rate" line contains actually the "field rate" (e.g. displayed "frame rate" of 59.94 for a 29.97 fps stream). Playback is fine, only codec information is wrong.
It is the case of any interlaced content I have tested (MPEG Video, H264).
