Forget that - VDR is in Transfer-Mode in your case, so setting any
additional PID and starting the cLiveSubtitle is just wrong.

The basic problem, as Reinhard pointed out, is that Transferring()
doesn't return the right value at this time, because the transfer
player hasn't been attached, yet.

This change determines the Transferring condition from the fact
that the actual device is different than the primary device, which
is already the case at this early stage:




I hope this doesn't have any other side effects...

Hmm, this might break vdr-xine. I remember a discussion which led
to the introduction of cDevice::Transferring(), but I'm not sure
whether I was using the same code before, which is now used to
implement this function.

As I'm currently busy with other things, I won't find time to
test this change the next days.

Bye.

Can somebody else with vdr-xine please test whether this works?

Although I don't see how this change could affect vdr-xine.
But it should be checked, anyway.

I have tested this with xineliboutput and have not encountered any 
problems. And it seems to have also fixed whatever it was that was 
causing the error messages.
