Problem: TechniSat SkyStar S2 (aka SS2 ver 3.3, DVB-S2 capable) shows black screen with channels from most DVB-S2 transponders in MediaPortal.
Reason: Inability of SS-S2 to handle full TS from high bandwith DVB-S2 transponders (most of them) due to perfomance limitations.
Solution: implementation of hardware PID filtering of SkyStar2 family in MediaPortal.
Pros: less work for TS analyzer/writer -> stability, balm for unhappy SS-S2 owners
Cons: TechniSat techsupport/marketing are far, far away from satisfactory -> no will to support their products But it is possible to help those customers who already made this mistake...
This card (assuming WDM drivers) is detected by TVServer3, scans transponders (DVB-S2 too), founds channels. Nothing unusial - this is "DVB-S2 enabled" SkyStar2, unified WDM drivers (4.5.0 and up) are handling all DVB-S2 specific: no need for application to switch explicitly to 8PSK. The same SDK, even VEN_ID and DEV_ID. Good backward compatibility.
But with MP the screen is black on most DVB-S2 transponders. Timeshift buffer shows mass discontinuity errors. Studying this problem I found out that SS-S2 can not process full TS from most DVB-S2 transponders due to performance limitations. Using hardware pids filtering can eliminate this problem.
Currently HW PID filtering approach for SkyStar 2 family is almost done but commented out.
It's high time to start using it.
