Technotrend C-1500+Technotrend CI+Conax CAM
I finally received my Technotrend CI module + Conax CAM order. So now I have the following hardware working (with some minor tweaks below): Technotrend C-1500 + Technotrend CI module + Conax CAM. These are my software versions: Fedora 12, kernel 2.6.32.21-168.fc12.i686 and MythTV 0.23.1.
Initially, I had some issues with recordings sometimes failing with the following error message in mythbackend.log:
2011-01-18 21:48:18.268 PID 0x1f9c status: Encrypted 2011-01-18 21:48:18.798 PID 0x1f9b status: Encrypted 2011-01-18 22:00:07.363 PID 0x44d status: Encrypted
Once I got this message, all subsequent recordings failed. What I quickly discovered was that if I restarted mythbackend, then the recordings would start working again. There seems to be some issue with the CAM or mythtv going into an invalid state if the DVB card/CAM is kept open for a long time.
So I changed the following mythtvsetup options under “2. Capture cards“:
Open DVB card on demand -> turned on Use DVB Card for active EIT scan -> turned off DVB Tuning Delay (msec) -> 2000 Tuning timeout (msec) -> 5000
MythTV EIT data not working
After I did a new channel scan in MythTV 0.23.1 I discovered that I didn’t get any EIT data from the DVB-C network anymore. I’m in Helsinki (Finland) and using Welho cable provider. So, I basically went through the same process as this guy, creating channels.conf files and so on. Eventually I discovered his page, which solved the issue of not getting EIT data. I did some more research into this and how to potentially solve it in other ways.
Solution #1 – Do a Full Scan (Tuned)
So, what worked for me was what he describes in his post, i.e. to do a Full Scan (Tuned) with the following parameters:
Frequency: 162000000 Modulation: QAM_64
When I look closely, those are the values for a few of the channels in my channels.conf file:
