All,
I got p2p working. I set the p2p bit and changed the device to Point
to Point and got it working. I don't know why it wasn't working
before. Maybe after I powered off the STB it made a difference (I saw
a couple of posts about turning off/on the STB)

Now I can't change channels. (ain't that just the way. Channel
changing WAS working before!)
I had determined earlier that I needed to set the node when changing
channels, 6200ch didn't default to node 0.
 i.e.:

6200ch -n0

And I placed this in the channel changing section in mythtv-setup. It
worked fine before. Now it doesn't work.

So, I made a bash script to accept a channel number (thinking maybe
"-n0" was getting lost). Now, I can change the channel with this bash
script outside with either user root or mythtv. That is, I can run FE,
change the tuner to the DCH3416 and view the video/audio just fine. I
can go to a terminal and change the channel of the STB fine. Works
honky-dory. I just can't change the channel INSIDE the FE.

I'll continue to search for the answer. If you have any insights,
please let me know!

thanks for your help!
