Yes, there is an additional patch for dvb cards, see 
but this one is not ready for CVS because of the problems with the 
"double free or corruption" error. I don't know yet why this happens.

Maybe somebody can give me a hint?  Add


in static void pmt_cb() (in file libs/libavformat/mpegts.c)

just above the line if (!pmtInList(ts->pmt_pids_old,pid)) {

so that the data stream will be added.
