Sources keep losing type

Hi

Currently running latest Eden version and Apple f/w 5.0.1.(4224).

Every day 'Movies' and 'TV shows' disappear from my media menu . This is caused my each source somehow losing it's contect type - If I manually edit each source and change content type to movies/tv shows etc I get the Video andn TV Shows options back but the next day the selection is reset to nothing and so i only get Videos, Music and Pictures options.

Any ideas?

thanks

Matt
