Sorry for not getting back to you on this sooner.

This is a bit tricky, I'd really like to have a DVD that uses these features
to verify with.   Your test are nice but I'd like to know see another player
and using a disc that isn't masterd by 'dvdauthor'.

I'll scan my own dvd for any use of this, at least playback mode of random
or shuffle is not common. Need to write a scrip to help me though ;-)

It's quite possible that these are swapped.. libdvdread is (or was) mostly
guessing... so unusual features are more likely to be wrong.

Not very nice to start charging for this I think... I don't really have
the time to make web pages though.
