What is odd about it is once i have run MythTv i can no longer capture the stream with the python script until i reboot the Ceton. This may very well be why it never worked before (Me starting Myth and never rebooting afterwards). As soon as MythTV attempts a recording the program information disappears and I am unable to tune any channel from the Ceton Webpage. I am using 192.168.180.1-RTP.0 in the backend setup.

When using the default configuration the USB tuner IP is 192.168.180.1 while the rest of my local LAN is 192.168.0.xxx.
