Tomi,

AIUI, some DVB cards/drivers cause failures with certain usage 
patterns--such as those used by EIT collection--especially when you have 
multiple cards in use at the same time.  So, please try disabling "Use 
DVB card for active EIT scan" on all but one of your capture cards.  
That may fix both of the above problems for you (and will still allow 
EIT collection when not recording, but using one card instead of 3).  If 
not, please test whether disabling "Use DVB card for active EIT scan" on 
/all/ your capture cards "fixes" the hangs for you.  If so, it means 
that your hardware/drivers don't like doing the EIT thing--and although 
not ideal for you (as you would only get passive EIT collection), would 
give us a better idea of what's happening (at which time we can present 
options).

Thanks,
Mike
