You only have three tuners. 2 on the 500, one on the 150. 

Yes, they have multiple connectors. Yes, technically the composite video
input isn't a tuner connection. It's an encoder.  No, that card can't
encode from both the coax and composite connectors at once.

And Myth currently doesn't have a good concept that two program
sources are available from one tuner device, but that only one
of them can be active at a time.

The first of these cases is correct.

Now, your cable box is presumably a superset of the clear analog
cable channels, so just configure that. That gives you the
maximum availability with the hardware you have.

You can replace your 150 with another 500, and put one of the
tuners there on the cable box and the other on the raw cable
feed. That will work, too.


Every time you give up a right, the terrorists win.
Tyranny is something that creeps up on you.
