It is late here now and just for a first look.

The second Composite you should get over the S-Video Connector, either
with a S-Video signal or with an S-Video to Composite adapter connected.
(Not so important, but people wanting to connect two Composite sources
don't have to plug connectors if this is present)

That must be further investigated.

With only one single hybrid tuner you can use analog and DVB-T
simultaneously only, if the condition is given that analog comes from an
external source like a VCR over Composite or S-Video. (needs packed
formats, planar don't work!)

It is the mentioned RF switch on current LifeView and Asus stuff.

Though a separate firmware eeprom and that PIC is a i2c IR controller
also found on the other LifeView cards. There are patches from Eddi for
the Trio remote, but not in master yet.

Thanks for your efforts.
