Yes, you're right, I wasn't specific enough: this applies only to
player which leave the video running live in foreground.

There are different play modes which a player can use:
pmAudioVideo (used by dvd,vdc & vdr player):
  not affected by timers
pmAudioOnly (mp3 with background mode live):
  if VDR isn't tuned to the recording channel -> device tunning
      makes player fail (not audio source memory)
  if VDR is tuned to the recording channel -> player aborts due
      to started tranfermode
pmAudioOnlyBlack (mp3 with background mode black):
  theoretically not affected by timers, but due to a "bug" in VDR
  up to now the same as pmAudioOnly.
  You can apply the small patch below to resolve the problem for
  this mode.
