- 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).
