[mythtv-users] Ceton Infinitv USB issues

Tue Feb 26 04:07:02 UTC 2013

Guess i spoke to soon. Updating to the latest Beta firmware for the Ceton
USB and running back through the python client I am now able to capture the
stream!

Not entirely sure what changed but unfortunately MythTV is still not
capturing the stream. 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.

I can see the rtp session getting created when I try to watch Live TV in
Myth:

@bun2:~sudo /bun2/bin/infinitv_usbd

Starting infinitv-usbd 0.1.0
found infinitv (/sys/devices/pci0000:00/0000:00:12.2/usb1/1-5)
rtp setup 0
rtp destroy 0
rtp setup 0
rtp destroy 0

MythTV still complains about no recorder...

Current testing is being done on Ubuntu 12.10 so I may try my 12.04
installation tomorrow.
