Version 1.7.5vdr-1.7.5

- Fixed a hangup when replaying a TS recording with subtitles activated (reported
  by Timo Helkio).
- Fixed handling the 'new' indicator in the recordings menu for TS recordings
  (thanks to Derek Kelly).
- Added cap_sys_nice to the capabilities that are not dropped (thanks to Rolf
  Ahrenberg).
- Updated the Italian OSD texts (thanks to Diego Pierotto).
- Added cRecordingInfo::GetEvent() (thanks to Marcel Unbehaun).
- Improved synchronizing the progress display, trick modes and subtitle display
  to the actual audio/video. This now works independent of any buffer sizes the
  output device might use.
  + The cBackTrace class has been replaced with cPtsIndex, which keeps track
    of the PTS timestamps of recently played frames.
  + cDevice::GetSTC() is now required to deliver the STC even in trick modes.
    It is sufficient if it returns the PTS of the most recently presented
    audio/video frame.
  + The full-featured DVB cards need an improved firmware in order to return
    proper STC values in trick modes (thanks to Oliver Endriss for enhancing the
    av7110 firmware).
- Adapted cFrameDetector::Analyze() to HD NTSC broadcasts that split frames over
  several payload units (thanks to Derek Kelly for reporting this and helping in
  testing).
- Modified cFrameDetector::Analyze() to make it process whole frames at once, so
  that file I/O overhead is minimized during recording (reported by Günter
  Niedermeier).
- Added command line help for the '-i' option.
- Fixed cDvbPlayer::NextFile() to handle files larger than 2GB (thanks to Jose
  Alberto Reguero).
- Improved replay at the begin and end of a recording. The very first and very last
  frame is now sent to the output device repeatedly until GetSTC() reports that it
  has been played. cDvbPlayer::Action() no longer calls DeviceFlush() (thanks to
  Reinhard Nissl for making sure vdr-xine no longer needs this).
- Added missing '[]' to the delete operator in cMenuEditStrItem::~cMenuEditStrItem().
- Added missing virtual destructor to cPalette.
- Now freeing configDirectory before setting it to a new value in
  cPlugin::SetConfigDirectory().
- Fixed a crash when jumping to an editing mark in an audio recording.
- Fixed the 'VideoOnly' condition in the PlayPes() and PlayTs() calls in
  cDvbPlayer::Action() (thanks to Reinhard Nissl).
- cDevice::PlayTs() now plays as many TS packets as possible in one call.
- Making sure any floating point numbers written use a decimal point (thanks to
  Oliver Endriss for pointing out a problem with the F record in the info file of
  a recording).
- Fixed detecting the frame rate for radio recordings.
- Added missing AUDIO_PAUSE/AUDIO_CONTINUE calls to cDvbDevice (thanks to Oliver
  Endriss).
- No longer writing the video type into channels.conf if VPID is 0 (thanks to
  Oliver Endriss for reporting this).
- Improved efficiency of cEIT::cEIT() (thanks to Tobias Bratfisch).
