Scan Result - OK, Services Found, No channels

Tim Torrey

Configuring new setup of Ubuntu Server running TVHeadend. Have 2 capture cards in the system and one is setup and working great. The ATI HDTV Wonder is giving me some issues. Originally the card was not initializing and I used this information to load firmware (http://pyther.net/2012/07/nxt2004-firmware/). Then rebooted and enabled the card again. Muxes are scanning and showing as scan result ok, services found, but no channels are being found.

If there is some command output that would be useful in helping troubleshoot please let me know the exact command you want run and I will post the output.

Thanks in advance for anyone that can help.

Have you tried anything other than Tvheadend to scan? If "dvbscan" is able to scan & find channels then it may be a bug with Tvheadend if not it may be your hardware. I know it does has issues with ATSC but it should find services.

You could open an issue and provide a trace during scanning see [[Traces]] on how to do that (remember to remove any personal info).

Installed and attempted to run dvbscan but it fails with:

Failed to open frontend

htpc@htpc:/dev$ dvbscan -adapter 0 /usr/share/dvb/atsc/us-ATSC-center-frequencies-8VSB

Failed to open frontend

In case it helps -

htpc@htpc:~$ ls /dev/dvb/ -o
total 0
drwxr-xr-x 2 root 120 Sep 26 23:38 adapter0

drwxr-xr-x 2 root 120 Sep 26 23:38 adapter1

Make sure that Tvheadend +isn't+ running & your user has video group perms, try using it with sudo.

I stopped tvheadend and then ran the command which seemed to run but didn't output anything. Here is what I ran and it just came back to the prompt:

htpc@htpc:~$ sudo dvbscan -adapter 0 /usr/share/dvb/atsc/us-ATSC-center-frequencies-8VSB

htpc@htpc:~$

Does it work fine in Windows?
