Version 1.3.5vdr-1.3.5

- Fixed reading the EPG preferred language parameter from 'setup.conf'.
- Fixed switching to a visible programme in case the current channel has neither
  a video nor an audio PID.
- Fixed editing channels (SID now range checked) and creating new channels (NID,
  TID and RID are now set to 0).
- Fixed transponder handling to make it work with satellites that provide two
  transponders on the same frequency, with different polarization, like Hispasat
  at S30.0W (thanks to Thomas Bergwinkl for pointing this out). See man vdr(5)
  for details about the enhanced channel ID format.
- Since there appears to be no general solution for the UPT error yet, a recording
  now initiates an "emergency exit" if the number of UPT errors during one
  recording exceeds 10 (suggested by Gregoire Favre). Since the UPT error doesn't
  happen on my system, this has not been explicitly tested.
  The "preliminary fix" for the UPT error in VDR/dvbdevice.c has been disabled
  by default, since it makes channel switching unpleasently slow. If you want
  to have that workaround back, you can uncomment the line
  //#define WAIT_FOR_LOCK_AFTER_TUNING 1
  in VDR/dvbdevice.c.
- Adapted the 'sky' plugin to use the actual channel IDs, and to fetch EPG data
  from www.bleb.org.
- Limited automatic retuning to devices that actually provide the transponder
  (necessary for the 'sky' plugin).
- Fixed handling receivers in the 'sky' plugin, so that a recording on the same
  channel won't interrupt an ongoing Transfer Mode.
- Added subtable ID and TSDT handling to 'libsi' (thanks to Marcel Wiesweg).
- Fixed some Russian OSD texts (thanks to Vyacheslav Dikonov).
- Added the 'running status' to the EPG events. This is necessary for implementing
  the VPS function for recording.
- Removed the obsolete 'present' and 'following' handling from the EPG data.
- The EPG data is now always kept sorted chronologically in the internal data
  structures. This also means that any EPG data retrieved through the SVRDP
  command LSTE is guaranteed to be sorted by start time.
- Now using the 'running status' in the channel display, so that a programme
  that has an end time that is before the current time, but is still running,
  will still be shown in the display (provided the broadcasters handle the
  'running status' flag correctly). This also applies to programmes that have
  a start time that is in the future, but are already running.
- Implemented an "EPG linger time", which can be set to have older EPG information
  still displayed in the "Schedule" menu (thanks to Jaakko Hyvätti).
- Added PDCDescriptor handling to 'libsi'.
- Implemented handling the VPS timestamps (aka "Programme Identification Label")
  for full VPS support for timers (provided the tv stations actually broadcast
  this information). The VPS time is displayed in the event info page if it exists
  and is different than the event's start time.
- Extended the SVDRP command LSTE to allow limiting the listed data to a given
  channel, the present or following events, or events at a given time (thanks to
  Thomas Heiligenmann).
- Fixed a typo in libsi/si.h (thanks to Stéphane Esté-Gracias).
- Timers can now be set to use the VPS information to control recording a programme.
  The new setup options "Recording/Use VPS" and "Recording/VPS margin", as well as
  the "VPS" option in the individual timers, can be used to control this feature
  (see MANUAL for details).
  Note that this feature will certainly need a lot of testing before it can be
  called "safe"!
- The "Schedule" and "What's on now/next?" menus now have an additional column
  which displays information on whether there is a timer defined for an event,
  whether an event has a VPS time that's different than its start time, and
  whether an event is currently running (see MANUAL under "The "Schedule" Menu"
  for details).
