Are you using xine's video output driver xxmc?

I experience deadlocks with this driver on either nVidia or Via EPIA
hardware. For example, when you replay a recording and press the pause
button: the pause symbol (OSD) will never appear on screen, input_vdr's
RPC thread blocks forever, vdr-xine waits for the RPC result while VDR
is caught in cXineOsd::Flush().

I'm working on this issue but still do not have a complete solution to
it: the deadlock is gone, but the OSD is still not shown on screen.

Bye.
