I made the code so that if it's not running Xine it should still work.
That said, I've never gotten a non-xine backend to work on my computer
so I haven't been able to test this out really, though there was a
period where I added features that used the xine_stream_t property of
phonon-xine, but still had phonon-xine's around that didn't have that
property and they worked fine (but that was a while ago). Basically I
never assume that pointer exists and check it first before using it.
And all I use it for is subtitle, audio channel and DVD menu
selection. You might try the latest SVN of Dragon Player which only
uses xine_stream_t for DVD menu selection.

I would also be interested to know if someone has tried the GStreamer
backend with Dragon Player. :)

Anyways great to see phonon-videolan progressing... it would be
awesome if all three platforms could use the same backend. :)
