Hi,

I would say yes. I have two dvb-c tuners installed in my backend and I see EIT updates comming in from both cards at the same time.

I even have a munin script that monitors the last EIT update per tuner:- http://mail.planet-ian.com/munin/planet-ian.com/alpha2.planet-ian.com/MythtvLastEIT.html

Thank you for your reply.

I have had some tuning problems that I thought might have been connected to active EIT scanning on all cards, but it looks like I have resolved that issue now.
I will set active EIT scan on all cards again and see how it goes.
