Sadly, same behavior as S2API V4L-DVB current branch. No lock on 30000 3/4 channels. It achieves a 0.5 second jittery sound but no image. It seems the driver is struggling to correctly lock on that channel, but doesn't get there in time... Or maybe the hardware... Dunno... Channels like ASTRA HD+;BetaDigital:11914:hC910M2O35S1:S19.2E:27500:1279=27:0;1283=deu:0:0:131:133:6:0 PREMIERE HD,PREM HD;PREMIERE:11914:hC910M2O35S1:S19.2E:27500:767=27:0;771=deu,772=eng:32:1837,1833,1834,9C4:129:133:6:0 DISCOVERY HD,DISC HD;PREMIERE:11914:hC910M2O35S1:S19.2E:27500:1023=27:0;1027=deu:32:1837,1833,1834,9C4:130:133:6 work just fine.

BTW, I think the channels above that don't work have a 0x0B stream indication. Satellite operators are misleading on the stream (h.222) when in fact they are h.264. Read that were on the ML. Don't know if it affects anything, but hey... I have to try everything! ;) I'm available to any tests necessary to fix this once and for all, if possible. Just let me know. Thanks for all your hard work.
