HISTORY

@ -8450,3 +8450,5 @@ Video Disk Recorder Revision History
- Made cRecording::GetResume() public (suggested by Stefan Braun).
- Fixed setting the read index in cDvbPlayer::Goto() in case Still is false.
- The function cDvbPlayer::Goto() now automatically calls Play() if Still is false.
- Added support for LCN (Logical Channel Numbers), which plugins may use to sort
channels (thanks to Rolf Ahrenberg).
