Hi
Several weeks ago I added a CCTV card to my work MythTV system in the hope of running Zoneminder on the same ox as my Backend server which is idle for most of the time.  The card I added has 4 SAA7134 chips on board and is detected in by Mythbuntu successfully, Zoneminder setup was stet raight forward and I can view my couple of CCTV cameras perfiectly.
The same cannot be said unfortunately for Mythtv, since adding the card I can no longer tune in my Hauppauge DVB S2 card to any satellite channel, keep receiving a channel change failure error on screen, see backend log below.

I have tested the scan utility from the command line and can detect all the channels as originally scanned, I have removed the cards from Mythtvsetup and re-added it without success. If I remove the SAA7134 card I instantly get all my Sat channels back in Mythtv :-( I also have Hauppauge Nova DVB-T card with local Irish channels which is unaffected by the Zoneminder hardware?

Anybody got any ideas as I really want these two systems to play nice ?


Many thanks for reading.

Are you running 32 or 64 bit OS?

If you are running 32 bit it is possible that your system is running out of virtual memory.

Look for something like this from dmesg:
[ 15.863906] vmap allocation for size 16781312 failed: use vmalloc=<size> to increase size.
