I'm fairly sure the mode "PAL" came from the DirectFB readme.
With softdevice -vo dfb:mgatv, the first head (I've still got a
monitor connected) displays the text output of directfb/vdr and also 3
copies of the video stream with the wrong colours. With -vo dfb: the
console text goes purple and there is no video visible on the first
head.
2nd head display is identical, except -vo dfb: is marginally sharper
with small white text on black, while -vo dfb:mgatv looks almost
anti-aliased. The difference is slight, but exists.

I don't know much about this sort of thing, but surely the sync signal
must exist, otherwise I would see scrolling images?
