 The main issue here is actually ccextractor's buffering of input.
 FILEBUFFERSIZE is defined to be 16MB which, at the script's suggested
 bitrate of 4.5Mb/s, takes around 30s to fill.  Changing FILEBUFFERSIZE to
 something smaller, like 1MB, makes it much more practical for Live TV and
 in-progress recordings.
