If you can get the Service Information for this particular channel your card is tuning correctly (assuming that they don't use the SDT-other tables). Maybe only Audio and Video PID are not correct.Seems that mostly Code rate high priority, Bandwidth and TPID was set wrong. But as I didn't tune myself that's not surprising...
I was trying that before, but didn't get it working. I thought thatPlease use the simple tools for debugging, e.g.: $ DVB/apps/szap/tzap c5
