In the DTV processing of keyframes, it was calling SetPositionMap
instead of SetPositionMapDelta. This means that it was trying to
delete/insert the position map data for the *entire* show,

While a ringbuffer is still necessary to prevent the overruns, this fix does
mean that the ringbuffer size can be much smaller. In a preliminary test, I
saw a maximum of 4.7MB used after an hour of recording three shows. These
shows were just upconverts and not true HD, but that is

The upconverted shows are not stretched. They are pillar boxed. That much
black area should be easily compressed, so I assumed that the station would
dial down the bitrate
The concept of upconverting is broken in itself, and from the example I have
seen here the bitrate is fixed
