First off, did you go into mythtv-setup and change the IP address to
192.168.1.112?

You specifically mention that it locks up when using RTP. Have you
tried configuring myth using the /dev entry rather than RTP, and does
that work?

And how did you accomplish bridging? I remember when I was first
learning to setup bridging, I managed to find a way to do it where the
ceton was bridged to outside computers but was inaccessible locally
(don't ask how I did it...I have no clue). Perhaps you did something
similar?

To test it, ssh into your myth system. Then use the nc or netcat program:
nc 192.168.1.112 80

When you start it you will get a blank prompt. Send the following:

GET /get_var.json?i=0&s=diag&v=Host_IP_Address

and press enter. You should get back something like this:

1c
{ "result": "192.168.1.112" }
0
