Hmm... this patch shouldn't be causing troubles for an application that
only uses DVBv3 call. Is Kaffeine filling the DTV_DELIVERY_SYSTEM with
SYS_UNDEFINED (0)?
If so, then Kaffeine has a bug, as it is requesting a non-existent
delivery system.
Could you please turn on the dvb-core debug, and see if it is trying to
do a DVBv5 call with DTV_DELIVERY_SYSTEM?
Thanks,
Mauro
