HVR-2250 Channel Mapping

[cjaffree]

I'm running an Hauppauge WinTV PVR 150 and an Happauge WinTV HVR-2250. I've configured all three tuners to use the EPG. On the digital tuners, I've mapped some of the digital channels to channel numbers in the provider's (Comcast) lineup on one of the digital tuners, but when I attempt to map to the same lineup channels on the other digital tuner, they are not available. All the other (non-mapped) channels are visible and available to map to.

What I'm wanting to achieve here is to have all the digital versions of the major network channels available on both digital tuners so that favorites can be recorded in digital HD (up to two programs simultaneously). With the channels mapped on only one tuner, one program gets recorded in HD and the other must be recorded on one of the analogs.

I've attempted examining the .frq files to see if I can copy information from one to the other, but the mappings don't seem to be contained there.

Can anyone recommend a better way to achieve the desired result?

Solved.
Went back into channel mapping and read more thoroughly this time to find out mapping applies to 'ALL sources using this lineup'.
