#1893: Summary of DVB-S table oddities in NA
--------------------------------+-------------------------------------------
 Reporter:  yeasah at schwide.net  |       Owner:  danielk
     Type:  defect              |      Status:  new    
 Priority:  minor               |   Milestone:  0.20   
Component:  dvb                 |     Version:  head   
 Severity:  medium              |  
--------------------------------+-------------------------------------------
 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.
