The aspect ratio of the screen is wrong (picture vertically expanded) when you play a wide picture even though you set “TV DISPLAY” in the SETUP menu to "16:9".
• If you connect the system with the SCART cable, connect directly to the TV. Otherwise the auto switch function of the aspect ratio for the TV may not work.
• If the TV is not connected with a SCART cable to the HS, or if the auto switch function does not work you should turn the TV to "16:9" (if possible with your TV).
• Depending on the TV, you may not be able to change the aspect ratio. In that case (TV not adjustable to 16:9) do not select "16:9" in the TV Display. Then, no change of the aspect ratio is needed.
The volume goes down automatically and cannot be increased.
• The internal temperature is too high. Wait approximately one minute for the amplifier to reach normal working temperature.
The subtitle language cannot be changed when you play a DVD.
• Multilingual subtitles are not recorded on the DVD.
• Changing the language for the subtitles by the Subtitle button on the remote or the Subtitle line in the Player Menu is prohibited on the DVD. In that case the subtitle language must be selected by the main menu on the DVD.
The subtitles cannot be turned off when you play a DVD.
• Depending on the DVD, you may not be able to turn the subtitles off.
