DVB only allowing single recording with 2 Avermedia tuners

[ian.cunningham@…]

I have 2 Avermedia tuners [volar-x & A16D] which have played nice up till v 0.27

I now, cannot get them to record simultaneously now regardless of how I try to even though they are both receiving correctly. Whatever I try I always show a conflict with one or the other even when I specify a different card for each recording, something myth took care of so well previously If any info apart from the dmessg below is required please email me & I will supply them thank you for your support

Relevant Dmesg showing how the cards load:

[Karl Egly]

Sorry for taking so long to get to this ticket. Is this still an issue?

It sounds like a configuration issue which can be handled better (and hopefully faster) in our troubleshooting forum at ​https://forum.mythtv.org/viewforum.php?f=36

Please verify that both cards are properly configured and connected to the same video source.

(fixed formatting of the dmesg while here)
