[mythtv] [PATCH] Multiple playback with Xv

[Pigeon]

Hi,

    I sometimes run multiple mythfrontends, one for watching recording,
another for perhaps browsing and deleting recordings, etc. And seems
that it's not able to use multiple Xv for playback properly...

    Here's the patch to make it work. I imagine there could be a same
kind of patch for XvMC as well, but I don't have XvMC therefore I
couldn't patch/test it.



Pigeon.
