@psycik you would need to get original-air-date into there, or valid Season and Episode numbers using episode-num
something like <episode-num system="xmltv_ns">6.45.</episode-num> would be the value for that episode (season.episode.part indexed from 0) which translates to S07E46 (notice the trailing . and the lack of part in the example.
You can read more about this here http://xmltv.cvs.sourceforge.net/viewvc/xmltv/xmltv/xmltv.dtd
Without PMS being able to detect that it is an episode, it will fallback to type=Movie
