You need to have separate video sources for each channel set.

I have Comcast cable as my only input but I have to define it as three
separate video sources, once for an HDHR, once for a PVR-150, and once
for a firewire connection to a STB.  The channels available to each
type of tuner are very different even though ultimately they're all
reading from the same cable.
