HISTORY

@ -4395,3 +4395,9 @@ Video Disk Recorder Revision History
- The "Blue" key in the "Timers" menu now displays the EPG info of the event the
selected timer will record (if available). The "On/Off" function has been shifted
to the "Red" button. Editing a timer is done by pressing "Ok".
- When determining which event a timer is going to record, all available events
in the future are now taken into account (no more limit to 4 hours in the
future). This has been done so that the event info is available in the "Timers"
menu when pressing the "Blue" button. In order to avoid unnecessary work, each
timer now has its own timestamp to control whether its schedule has changed
since the last time its event has been set.
