How can I make a mixed audio/video playlist?
I would like to make a playlist of music videos. iTunes seems to consider "music videos" as a separate type than video files. The problem is that some of my music videos are detected by iTunes as formal "music videos" while others are detected as "movies". While I can add them all to the same playlist, I can only play the playlist as one of the two types, and it will ignore the files of the other type. For example, if I access the playlist through my music playlists on my iPhone, it will only play the music videos that iTunes thinks are actual "music videos" and will not play the ones that iTunes thinks are "movies". Same problem in the opposite direction if I play the playlist through the movie/video interface.
How can I get them all to play together? They are ALL videos, and all in the same format (.mp4), so I'm not sure why iTunes is so confused.
