PAT and PMT are per MPEG-2 spec and should be the same for DVB and ATSC (well, some descriptors might be different but the structure should be equal), however the other tables that dvbscan evaluates (SDT and NIT) do not exist in ATSC (they have other tables). I am confident that dvbscan at least should not get a timeout for PID 0, and should be able to parse the PAT, and then get and parse the PMTs, thus giving you the PIDs. OTOH the PAT you posted is invalid accoring to MPEG-2 ... (00 b0 0d 05 53 c5 00 00 00 01 e0 20 08 65 0b 88 ....S...... .e..) Johannes
