Comment (by Klaas de Waal):

 This problem can be reproduced with today's master. The only difference is
 that the wait time before the recording starts is now 15 seconds instead
 of 10.

 Reproducing is trivial:
 - start a recording (either via schedule or by pressing "R" in the guide)
 - the recording is now displayed green in the "Watch Recordings" page
 - stop the recording
 - the recording is now displayed in white in the "Watch Recordings" page
 - give playback command
 - NOW wait for 15 seconds and watch the black screen
 - then playback starts

 As described, when the playback command is given one minute or more after
 the recording has stopped the playback starts immediately.
