No.

Well, as VDR crashes (maybe due to a bug in vdr-xine), I think that a 
backtrace would be most helpful.

To get one, please compile both VDR and vdr-xine with debug information. 
Therefore, I modify both Makefiles and change the option, which are feed to 
the compiler, e. g. for vdr-xine:

	#CXXFLAGS ?= -O2 -Wall -Woverloaded-virtual
	CXXFLAGS ?= -O0 -g3 -Wall -Woverloaded-virtual

And for VDR:

	#CFLAGS   ?= -O2
	CFLAGS   ?= -g3 -O0

	#CXXFLAGS ?= -O2 -Wall -Woverloaded-virtual
	CXXFLAGS ?= -g3 -O0 -Wall -Woverloaded-virtual

Then I run vdr with ddd (a GUI for gdb):

	video:/soft/src/VDR # ddd ./vdr

And within ddd:

	run '-Pxine -r'

Later, when VDR crashes, you should be able to see where this happend and you 
should also be able to retrieve a backtrace via the menu, to determine how the 
faulty location was reached.

I hope this little debug HOWTO yields enough data to fix this issue.

Bye.
