Got this working. The problem was being caused by this error in mythbackend:

2010-06-12 14:27:08.739 FireChan(0023A2FFFE96C43D), Error: Model:
'DCX-3200' is not supported.

                        Perhaps you should re-read the installation
instructions?
2010-06-12 14:27:08.813 mythbackend: No capture cards are defined:
Please run the setup program.

But the above tests indicate that it works...so I added it:

 }

Now the backend attempts playback, but it fails to change the channel.

I read about 6200ch in the wiki, but it didn't want to recognize my box,
though it is supposed to work with this model.
6200ch returns the following model and vendor ids for my box:

node 1: vendor_id = 0x000023a2 model_id = 0x0000f760

So I added:

Then set the 6200ch binary as my channel changer in mythtv setup.
Everything appears to be working. Maybe this will help someone else with
this box.
