steerable-vdr-xxx.diff
  Apply this patch to avoid vdr restarting after starting a recording on a
  different satellite  (see the main README file).

sort-by-source-vdr-xxx.diff
  Apply this patch if you want:
  1) to always see the satellite position in the channels list (so you know
     in advance if the dish is going to move)
  2) to sort channels by source (i.e. pressing 0 will switch between
     number->name->provider->source+number->source+name->source+provider,
     an asterisk in each entry will show that the list is sorted by source)

Source-dependant-NewChannels-Insertation-vdr-xxx.diff
  Apply this patch if you want new channels added depending on the satellite
  (if a section "New channels @ xx" already exists, new channels will be put
  there, otherwise a section with the current position will be created).
