Hi Vijet,
Some PSI tables locate in special PIDs, pls refer to 13818-1; and you also can analyze PMT first to get information about whatever PIDs carrying the table you want to record. Hope that can answer your question :)
Best regards,
Kurt

Hi,
Sorry to interrupt your discussion but I have a question regarding recording of MPEG2 streams.
As Kurt said, if you set pesfilter with output as DMX_OUT_TS_TAP and pass the pid, it will record the streams corresponding
to that pid. So, if I pass audio and video pid, then it will record only the audio and video streams.
I wanted to know how to record the DVB SI/PSI tables corresponding to the streams I'm recording.
Do I have to pass the pids of the tables I want to record or is there some other way?
Right now, I'm using the pid value 0x2000 for setting pes filter which is proving to be computationally intensive and consuming lot of CPU.
Please help.Thanks in advance,

some SI/PSI Tables seems to me cost-effective compared to handling
40Mbps of a DVB Stream (that's what was my example ... DVB-S Streams...)
