Stef, I have two SkyStar 2 PCI cards, a Freecom DVB-T USB2 stick and a Hauppauge DEC2000-t USB1.2 DVB-T receiver. All work happily at the same time even with the first three recording an entire transponder/multiplex each though the hard drive can struggle to keep up, the Hauppuage can only record one VPID and APID at one time unfortunately. I think 4 devices is the limit of the driver. This is all on a 550MHz Pentium PIII, even in the worst case there is still plenty of CPU to spare. I also use dvbstream, you cannot capture different PIDs to different files but if you install libdvb you will get the dvb tools which allow you to separate out the various channels into individual program streams once recording is complete, for example if multiple_pids.mpg contains BBC1 (VPID 600, APID 601) and BBC2 (VPID 610, APID 611), and maybe all the other channels on the BBC DTT multiplex: ts2ps 600 601 < multiple_pids.mpg > BBC1.mpg ts2ps 610 611 < multiple_pids.mpg > BBC2.mpg Obviously this means having a decent amount of hard drive space available. I did start working on a utility to fan out/duplicate a DVB stream containing multiple VPIDs and APIDs to multiple pipes, each being read by a ts2ps process filtering for particular PIDs. This would achieve what you are (and I was) looking for, but I never got round to finishing it - program clashes are rare and if they do happen then it is easier to use two dvbstreams with one using one device for one broadcast and another for the other. It would be more elegant to integrate the ts2ps functionality into dvbstream (to avoid using lots of pipes and duplication of a high bandwidth DVB stream) and it probably wouldn't be that hard either if you can find and factor out the core functionality in ts2ps. Then you could do: dvbstream .... 600 601 -f BBC1.mpg 610 611 -f BBC2.mpg .... HTH, Tim.
