seems like i had some hallucinations :-) The cinergyT2 behaves exactly like
the budget-ci: tzap does not expose the memory leak but dvbd does. It does not
matter if i grab the EPG with tv_grab_dvb or with "dvbrowse -p", after tuning
to all 6 transponders here in Nuernberg with dvbcat/dvbd, i have 10MB less
free memory.
