Version 1.1.11vdr-1.1.11
- Fixed an incomplete initialization of the filter parameters in eit.c (thanks to Jeremy Hall). - Fixed the 'newplugin' script for use with the NEWSTRUCT driver (thanks to Andreas Schultz for reporting this one). If you have already created a plugin directory and Makefile with 'newplugin', please apply the following patch to it: ------------------------------------------------------- --- Makefile 2002/06/10 16:24:06 1.4 +++ Makefile 2002/09/17 15:36:36 1.5 @@ -15,7 +15,12 @@ ### The directory environment: +ifdef NEWSTRUCT +DVBDIR = ../../../../DVB/include +DEFINES += -DNEWSTRUCT +else DVBDIR = ../../../../DVB/ost/include +endif VDRDIR = ../../..

The previously used files 'keys.conf' and 'keys-pc.conf' have been replaced by the file 'remote.conf', which holds the key definitions of all remote controls. - The LIRC remote control keys are now handled just like the keyboard and RCU keys. This means that you can use the lircd.conf file as is for your remote control, without the need of editing it to make the key names the same as used in VDR. When first starting VDR it will go into the "Learning keys" mode and ask you to press the various keys. The resulting key assignment will be stored in the file 'remote.conf'. Since I have no way of testing the LIRC support, I hope I didn't break it in the process... - While learning the remote control keys it is now possible to press the 'Menu' key to skip the definition of keys that are not available on your particular RC unit. - Fixed handling DVD subtitles in the SPU decoder (thanks to Andreas Schultz). - Avoiding restarts due to 'panic level' when switching channels on the primary device during EPG scan.
