Hello, All I've managed to hack together a ATSC channel scanner with PISP service table parser using the DVB API. I?ve tested it using the Air2PC card but I?d suspect that it will work with any ATSC card support under the DVB API. Basically, This allows you to view a channels call sign and it?s various audio/video PID information available.
