The file varies in size, from around 3MB to around 7MB for the 5 seconds. I have no idea if the PIDs are the correct ones, but at least they match the output from dvbsnoop: dvbsnoop -s pidscan --------------------------------------------------------- Transponder PID-Scan... --------------------------------------------------------- PID found: 0 (0x0000) [SECTION: Program Association Table (PAT)] PID found: 110 (0x006e) [PS/PES: ITU-T Rec.
