function to hand through the Level.
- Fixed checking for ttDolbyLast in cDevice::SetCurrentAudioTrack() (thanks
to Marco Schlüßler).
2007-10-12: Version 1.5.10
- Implemented handling DVB subtitles (thanks to Marco Schlüßler, and also to
Pekka Virtanen for writing the subtitle plugin, which helped in implementing
subtitle handling in VDR).
- The new remote control key "Subtitles" can be used to bring up the list
of available subtitles.
- The new setup option "DVB/Subtitle languages" can be used to define the
preferred languages for subtitles.
- Fixed selecting the audio track when pressing Ok in the Audio menu (thanks
to Marco Schlüßler).
- Implemented display of DVB subtitles in live viewing mode.
- Implemented subtitle track selection.
- Implemented bitmap color reduction and shrinking to display subtitles even
on devices that can't display the necessary number of colors.
- Added compatibility mode for playback of recordings made with the subtitles
plugin (with some help from Rolf Ahrenberg).
- The new setup option "DVB/Subtitle offset" can be used to shift the location
of the subtitles in the vertical direction.
- The new setup options "DVB/Subtitle foreground/background transparency"
define an additional level of transparency for the foreground and background
color of subtitles.
- Existing recordings made with the subtitle plugin can be given an 'X' record
in their info.vdr file, so that subtitles can be automatically selected upon
replay, according to the preferred language setup, as in
X 3 03 ger deutsch
(see vdr.5). Note that these entries need to be added in the proper sequence,
so that they correspond with the actual track languages in the recording.

Display subtitles = no If set to 'yes', the first available subtitles in the list
of preferred subtitle languages will be turned on when
switching to a channel that provides subtitles.
Subtitle languages = 0 Some tv stations broadcast various subtitle tracks in different
languages. This option allows you to define which language(s)
you prefer in such cases. By default, or if none of the
preferred languages is broadcast, no subtitles will
be selected when switching to such a channel. If this option
is set to a non-zero value, the menu page will contain that
many "Subtitle language" options which allow you to select the
individual preferred languages.
Subtitle offset = 0 Allows you to shift the location of the subtitles in the
vertical direction. The valid range is -50...50. This option
is only avialable if "Display subtitles" is set to 'yes'.
Subtitle foreground transparency = 0
Subtitle background transparency = 0
These define an additional level of transparency for the
foreground and background color of subtitles. Valid ranges
are 0...9 for foreground transparency, and 0...10 for
background transparency. By default the values as broadcast
