[Igor Nikanov]

Hi

from readme vdr 1.7.0
=========================================================================
  Note that the channels.conf file now supports additional parameters, so you may
  want to make sure you have a backup of this file in case you need to go back to
  the previous version of VDR!
=========================================================================

which difference between this describing ?
