HISTORY
@ -845,3 +845,5 @@ Video Disk Recorder Revision History
|
||||
- Changed the tuning code to use FrontendInfo to detect the type of DVB card.
|
||||
- Removed the recursion stuff from cThread (cMutex already does this).
|
||||
- Fixed handling the repeat function in the channel display.
|
||||
- Avoiding multiple EPG entries for the same event (thanks to Rolf Hakenes
|
||||
for some valuable information on how to do this).
