Subject: Version 0.90 - Modified the display of the channel group separators
 (thanks to Markus Lang   for this suggestion). - Added support for replaying
 DVDs (thanks to Andreas Schultz). See INSTALL for   instructions on how to
 compile VDR with DVD support. - Fixed replay progress display in case replay
 is paused while watching an   ongoing recording. - Ringbuffer uses semaphores
 to signal empty/full conditions. - Fixed calculating the timeout value in
 cFile::FileReady() (thanks to   Wolfgang Henselmann-Weiss).
