We've used the HVR-4000 for DVB-T and DVB-S with both tuners working concurrently but not explored the multiple frontend aspects at all to allow for intermixing of DVB-S & DVB-T etc.
Andrew, can you confirm that
a) you had the DVB-T part up and running?
b) with concurrently you mean that you had 2 'frontends' simultaneously viewing or recording?
c) you're doing this with 0810 and myth v0.21?
d) did you YES or NO have symbolic links in place to create /dev/dvb/adapter1 (/dev/dvb/adapter0 is present standardà
I'm digging on the mythtv-users list at the moment, and the more I come to realize that dvb-s or dvb-s2 for that matter is reported working, but I'm still waiting to see dvb-t confirmed yet.
Apart from that, I seem to recollect that simultaneous use is not possible. I'm not sure if we may mix up with multiplexing here - maybe you can clear this up.
Thanks for your assistance
