it checks table of frequencies that usually contains channels. Thou
dvb-c users need to check if modulation and symbol-rate are correct for
them (atleast for me modulation auto didn't work).

example commandline that worked for me:
vlc dvb:// --dvb-srate=6875000 --dvb-modulation 128

default symbol-rate is suited to dvb-s and is over limits for dvb-c, so
check given symbol-rate and default to somewhat common value if so.

Or else a timer callback might still be running when the caller frees
its resources, which is bad
