[mythtv-users] Ceton Infinitv USB issues

[michael helmer]

I have done some more testing and have found that in Windows Media Center I
have no problems watching live TV or recording four channels. The issue
with tuning all four tuners occurs after moving my Ceton USB behind Ubuntu
and starting Mythbackend (without triggering a recording). Once Mythbackend
is running I can usually tune two of the four tuners but recordings fail
and the signal level goes from -5 dBmv to -40 dBmv.

If I start Mythbackend and then reset the tuner all seems to be well. All
four tuners tune with a -5 dBmv but I am still unable to watch live TV or
record any channels. It also appears that once a recording fails the signal
level goes back to -40 dBmv.

All I can seem to get out of the logs when watching tv or recording is not
very helpful for troublshooting this issue. Maybe this means something to
someone else?

When I delete the failed recording the mpg file is not found and sometimes
is left in the recording directory with a 0 byte size.

I have been trying to figure out how to confirm streaming video without
using Mythtv and not having much luck. Namely Cetons client package. Has
anyone tried this before?

Confirming that tuner 0 is working and has a good signal level I run the
client script and use VLC to open a network stream to rtsp://
192.168.180.1:8554/cetonmpeg0 but nothing happens

@bun2:~/infinitv_client_1_2$ sudo python ./client.py -i 192.168.180.3 -t 0
-c 2004
