yea.. that's bad. You absolutely should be able to disable the DHCP server on your modem. Ugh.

My situation was that mythbackend started up prior to the HDHR obtaining a DHCP, so strangeness would happen.  I had to modify the init scripts to wait for the HDHR networking to stabilize before mythbackend starting.  However, this was several months back using 0.24.  I am not sure if any recent changes went into this area.

Which bring up another good point - "infrastructure" should not be on changing IP's. It's ok to use DHCP to configure them on boot, but things like all my manages switches and WAP's and HDHR are on assigned static addresses in DHCP. As long as DHCP is up and running (on a static IP based server) - those devices will always come up on the same address, not an assignment out of a pool.
