Regarding: > but a PAT is there, as "test_sections 0" demonstrated. > Are you sure azap was running and had a frontend lock? I ran dvb_scan with and without azap running (with a lock on the right) and had the same response. I have now toyed with the card on a windows machine and done a channel scan on that platform. I'll experiment with the frequencies and PIDs from that. My problems still come from the fact that I don't know which apps *should* work, since they weren't really designed for ATSC. Are you confident that dvb_scan should give me more verbose results? Thanks again, Jean
