If the pooling works as David described, that would be the better 
solution.  I have only one HDHR device, so I can't test that. However, 
this should only matter if other devices on the network access the HDHRs 
directly, since that would prevent MythTV from re-tuning the tuner in 
use by the other device.

To test that I would:

 1. Using a computer with the hdhomerun_config_gui, lock one of the
    tuners on one of the HDHRs.
 2. Using a second computer with hdhomerun_config_gui, lock the other
    tuner of that HDHR to a different RF channel.
 3. Set up MythTV to make two test recordings on two additional,
    different RF channels.

If MythTV successfully starts both recordings, the test is successful.

Scott
