No, no, no. If it was my reply to which you refer, I never mention
setting up two video sources.
Both tuners share a /single/ video source. One of the tuners is set to
get EIT data actively (in the background when not being used for
recordings/live TV) and the other can get it passively when being used
for recordings. Both tuners are able to provide EIT data for the same
video source - perhaps this is where the confusion lies?
When using identical tuner types, you only need to configure separate
video sources if you require each tuner to receive a different set of
channels from those available on the tuner (e.g. if one of the
physical tuners is more sensitive than the other(s) and has only
borderline reception on some multiplexes).
