[QUOTE="Adam792, post: 972681, member: 330868"] You're on the right lines - but the full multiplex (the single PID carrying the data) is what is encrypted, once that is decrypted the channels inside it are all clear; they're not individually encrypted. The way I tune them on my computer is: Tune the transponder and select a PID (e.g. PID 702 on 12548V) --> Decrypt this PID with the BISS key (using VLC's CSA tools) --> Pass the decrypted data to a tool I wrote myself which strips the TS packet headers (You have a full multiplex encapsulated within the data PID of the DVB-S2 transponder - e.g. in this example to get just the wanted data you have to remove the TS packet headers relating to the data PID 702) --> The data that comes out is just a full multiplex TS which can be watched in VLC/streamed out to UDP/dumped to disk. I don't know how similar to T2MI this is (I've not got any experience of T2MI/4T2), but from what I've read it sounds slightly similar - especially the part of having to strip the outer packet headers to get just the data inside.
