Version 1.7.8vdr-1.7.8

- The name of the function cDevice::GetVideoSize() wasn't very well chosen
  for its purpose of defining the optimum size of the OSD for the current
  output device. Therefore a new function named cDevice::GetOsdSize() has
  been introduced (suggested by Rolf Ahrenberg). Plugin authors should
  implement this function in classes derived from cDevice, if they are able
  to replay video. cDevice::GetVideoSize() still exists and should return the
  actual size of the video material that is currently replayed. Note that
  because of the many possible aspect ratios for video material, the type
  of the Aspect parameter of GetVideoSize() has been changed to 'double',
  and the Aspect parameter in both functions is named differently, because
  it returns different values (suggested by Reinhard Nissl).
  Thanks to Oliver Endriss for his input on calculating the Aspect factor in
  GetOsdSize().
- Fixed the way the OSD size is determined on full featured DVB cards (thanks
  to Oliver Endriss).
- Increased MAXOSDHEIGHT to 1200 (suggested by Nicolas Huillard).
- Removed limitation to PAL resolution from SPU handling.
- Checking fd_video in cDvbDevice::GetVideoSize() to avoid error messages on
  systems with no real primary replay device (reported by Martin Neuditschko).
- Added a note to cTsToPes::GetPes() about having to call it repeatedly, once
  it has returned a non-NULL value.
- Added MPEG 1 handling to remux.c (thanks to Ales Jurik).
- Fixed use of time_t in cEIT::cEIT() (thanks to Tobias Bratfisch).
- Added missing update of lastOsdSizeUpdate.
- EIT events are now only processed if a plausible system time is available, to
  avoid wrong handling of PDC descriptors (thanks to Tobias Bratfisch).
- Removed unused 'synced' member from cTsToPes (reported by Christoph Haubrich).
- Added a note to cTsToPes about all TS packets having to belong to the same PID,
  and that for video data GetPes() may only be called if the next TS packet that
  will be given to PutTs() has the "payload start" flag set (suggested by Christoph
  Haubrich).
- Added a note about the meaning of PERCENTAGEDELTA in cRingBuffer::UpdatePercentage()
  (thanks to Rolf Ahrenberg).
- The new setup option "Recording/Pause key handling" can be used to define
  what happens if the Pause key on the remote control is pressed during
  live tv (thanks to Timo Eskola).
- Added a note about cFont::GetFont() not being thread-safe.
- Fixed generating PAT/PMT version numbers in case the PIDs change during
  recording (reported by Reinhard Nissl).
- Updated the Ukrainian OSD texts (thanks to Yarema Aka Knedlyk).
- Fixed a memory leak when reaching the end of a recording during replay (reported
  by Reinhard Nissl).
- Fixed calling close(-1) in cUnbufferedFile::Close() (reported by Reinhard Nissl).
- Added a workaround for the broken linux-dvb driver header files (based on a patch
  from Tobias Grimm).
- Fixed handling the length of DiSEqC command sequences (reported by Reinhard Nissl).
- Fixed cOsdMenu::Display() in case the menu size has changed (thanks to
  Reinhard Nissl).
- Added some missing 'const' keywords to avoid compilation errors with gcc 4.4
  (thanks to Ville Skyttä and Ludwig Nussel).
- Modified cSVDRP::CmdGRAB() to avoid writing into const data (reported by
  Ludwig Nussel).
- Fixed calculating menu colum widths in case the font has a size other than the
  default size (reported by Reinhard Nissl).
- Added a plausibility check for the OSD percentage parameters
  to avoid problems in case the values are stored in the setup.conf
  file in a  wrong way.
- Fixed variable types in cIndexFile (reported by Udo Richter).
