[mythtv-users] Ceton Infinitv USB issues

I have been sticking to MCE at the moment as everything is functional
(except when i configure networking tuners). Oddly this does not work in
MythTV or using the python script in Linux. 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.

Ceton provides a "network tuner" configuration option in Windows which
bridges the Ceton device to your local LAN. In this case the USB tuner has
an IP address on my local LAN i.e. 192.168.0.8. This does not work in
Windows.

In both cases the the source port is 43012 and the destination port is 5001.

Just thought i would clarify. The behavior is odd and I cannot explain it.
