View Full Version : 9.1 upgrade, now pvr350 fails
November 25th, 2009, 05:32 AM
Since 'upgrading' to 9.10 the PV350 which is hooked to the cable box fails to do anything. The logs (thru mythweb) only show
"Canceled recording (Recorder Failed)"
When I go into live TV and change to that tuner it's the last thing the front end will do - have to kill it.
Both channels of the PVR500 work fine - though they decode directly and can't do the high channels.
The 350 was working perfectly in 9.04, and I've made no changes which should affect it.
Any help would be appreciated, I'd sure like to get this fixed as my system is crippled right now.

What messages do you see in the syslog (/var/log/syslog) and in the mythtv backend log (/var/log/mthtv-backend.log) when you try and record from the PVR350?

the backend log is no more informative

syslog doesn't have anything either. Though this event might be where I tried live TV

A friend of mine tweaked the firewire channel changer...seems this got blown up with the 9.10 'upgrade'

I can't reach my friend. Anyone have any bright ideas how to fix this or do I need to wait for him?
Cable box is a motorola DCH6200, we were unable to get it to work with the standard firewire channel changer, he tweaked something to make it work in 9.04. Now 9.10 has broken that.
Bright ideas? Sure would like to get my system fixed.

Really? no one has any idea how to fix this thing?

Finally fixed this, all my my lonesome.
Here's the keys to the kingdom in case anyone else runs into this problem.
First I had to make sure the channel changer script was loaded correctly, that is 6200ch is in the right place, it was. Then make sure it's the right version, it was not. So I compiled and updated the 6200ch.
Next it still wouldn't work. So I had to find out why. Reason is that there's a zillion different DCH6200 cable boxes and they have different internal ids. So, run plugreport to get the vendor and model id. Then edit the 6200ch.c and steal one of the vendor ids and model ids. Don't add another number, this won't work, just replace one.
Compile and copy to the usr/bin/local dir.
Test by seeing which node it's on with plugreport and using something like 6200ch -v -n 0 55
The -v is verbose, the -n 0 tells it node 0 and the 55 is the channel to change to.
If that works and you don't get an error message, go into backend setup and add the /usr/bin/local/6200ch -n 0 to the channel change line (in my case I had to add the -n 0 to address node 0).
Restart the backend.
Voila, it works.
Yeaaaa, I feel like such a computer geek god today.
(not really as the audio stuff is still screwed, but I'll fight that battle another day)
