Subject: Version 1.7.6 - cDevice::PlayTs() now syncs on the TS packet sync
 bytes. - Made MAXFRAMESIZE a multiple of TS_SIZE to avoid breaking up TS
 packets. - No longer resetting the patPmtParser in cDevice::PlayTs(), because
 this   caused the selected audio and subtitle tracks to fall back to the
 default. - The SVDRP command PUTE now supports reading the EPG data from a
 given file   (thanks to Helmut Auer). - Added cThread::SetIOPriority() and
 using it in cRemoveDeletedRecordingsThread   (thanks to Rolf Ahrenberg). -
 Fixed the MEGABYTE() macro to make it correctly handle parameters resulting
 in   values larger than 2GB. - Added cDevice::NumProvidedSystems() to
 PLUGINS.html (was missing since it had   been implemented). - Fixed
 distortions when switching to the next file during replay. - Fixed detecting
 the frame rate for streams with PTS distances of 1800, which   apparently
 split one frame over two payload units. - Added missing 'const' to
 cRecording::FramesPerSecond() (thanks to Joachim Wilke). - Any TS packets in
 the first "frame" after a cut in an edited recording that don't   belong to a
 payload unit that started in that frame now get their TEI flag set,   so that
 a decoder will ignore them together with any PES data collected for that  
 PID so far (thanks to Oliver Endriss for reporting chirping sound
 disturbences at   editing points in TS recordings). - cDvbPlayer::Empty()
 subtracts 1 from readIndex, because Action() will first   increment it. -
 Only storing non-zero Pts values in ptsIndex. - Added a note to the INSTALL
 file about using subdirectories to split a large   disk into separate areas
 for VDR's video data and other stuff (suggested by   Udo Richter).
