Description

Here are scans of PAT/NIT/SDT/EIT using dvbsnoop of providers listed on LyngSat? for North America. Various issues prevent tuning for some providers, as summarized below. This ticket is meant both as a description of what might be broken in actual use, as well as a description of the sort of real-world oddities that the DVB code should be able to handle gracefully.

Actual dvbsnoop logs are attached as a fairly large (~400K) bz2 compressed tarball.
