- add VO_INTERLACED_FLAG to get_frame
- do not trust progressive_frame for detecting NTSC 3:2, quote:
'the alternating progressive_frame encoding problem. This is a problem where the progressive_frame flag alternates between true and false every frame, when it really should have been set to "true" all the time.'
'There is a lot of content that is affected by this issue, because it's caused by a dumb decision by a very big company that made a very popular MPEG encoder. They've since fixed the encoder, but there are apparently still authoring companies that use it, because the problem is on a lot of high-profile current discs, like Disney's "Monsters Inc." and "Beauty and the Beast".'
