Hi all, I understand (thanks to the recent posts on the list) that it is possible to record multiple programs at once, so long as they are on the same multiplex. My question is, how do I do that using the DVB api? If I want to record a single programme (collection of PIDs) then I can filter them to TS_OUT_TS_TAP, and the pids will be automatically mixed into a new TS that I can read from the dvr device. I'm guessing if I try that with multiple channels (2 collections of PIDs) then I'd get a TS with both channels in it, and I'd have to do work to separate the two. One way would be to do the above, and write it out as 2 streams (filter each packet one way or the other, and rewrite the PMT etc as I go - sending a PMT into each stream). If I do that, which parts of the stream would I need to rewrite? Another approach would be to us TS_OUT_TAP, and do all the remultiplexing myself. Not sure how to go about that... and it sounds like if I go the TS_OUT_TS_TAP route then the driver does more work for me. What do people recommend? Thanks Matt
