I think I found a bug.
When mc-2.135 scans a TV show which is in a VIDEO_TS folder, it creates as many .nfo files as there are .VOB files. So instead of 1 episode and 1 .nfo file, it creates (say) 8 .nfo files and thinks I have 8 copies of an episode.
Easily fixed as I simply will remove all the extra .nfo and .tbn files, but it shouldn't do that. I would like it to treat it like a movie folder.
