@ -907,3 +907,7 @@ Video Disk Recorder Revision History
- Fixed handling file names that contain single quotes (') or dollar signs ($)
in the call to the shutdown command (option '-s') and the recording command
(option '-r').
- Improved error handling in the editing process; the resulting file will be
deleted if an error occured.
- A message is now prompted at the end of the editing process, indicating
whether the process succeeded or failed.
