--- Comment #1 from Andy Furniss adf.lists@gmail.com --- More testing shows that low Hz modes do still work - in all cases the /1.001 modes behave the same as the exacts.
50p and 60p = fail = no sound and mplayer behaves as is does if the device isn't there = playing too fast.
24p, 25i and 30i are working OK.
