I have inserted a counter into cEIT::ProcessEIT() just to see how many
EIT blocks are coming in. The result was overwhelming: on RTL and related
channels there's about 130 EIT blocks coming in within 10 seconds, while
on Pro7 and friends there are about 4300 EIT blocks in the same time
interval! This means that Pro7 is broadcasting over 30 times the EIT data
of RTL - no wonder VDR has a lot to do...
