So, this is a matter of LiveBuffer patch. But I don't understand why it 
was working when switching channels.

Anyway, to fix it properly, the following line in 
cXineDevice::SetPlayMode() most be adapted to LiveBuffer:

       m_settings.SelectReplayPrebufferMode(!Transferring());

For vanilla VDR, Transferring() reports the existence of a transfer 
thread which means, VDR sends Live TV to vdr-xine.

So, how could I detect Live TV in the case of a VDR with LiveBuffer patch?

Is there a way to automatically detect that the LiveBuffer patch was 
applied to VDR?

Bye.
