Changes for V1.6 (spitfires):
- Corrected recording calculation for UK TiVi (i.e. s/w v2.5.5)

- Append to log file rather than create afresh each run (it's in /var/tmp so will be cleare on a reboot)

Changes for V1.5 (TivoZA):

Changes for V1.4:
- Now detects a v2.5.5 system and alters the offset to avoid the
  in-use percentage appearing over the TiVo guy.

  is not always ready to accept requests when autospace is run from
  the startup scripts.

- Added error check for problems with FsId's in /Recording/InProgress

Changes for V1.1:
