Well, the OTA providers are doing it to the network feeds first, so I
don't see focusing on the cable providers doing it to the OTA providers
as the sole source of quality issues. The OTA providers also reencode
to add bugs, weather/breaking news crawls, etc., and they don't always
do a good job of that before feeding the signal to the statmuxer.
