- Added compiler options "-fPIC -g" to all plugins (thanks to Rolf Ahrenberg). - Fixed initializing the day index when editing the weekday parameter of a repeating timer (thanks to Marco Schlüßler). - No longer removing superfluous hyphens in EPG data - would become too language dependent to handle all kinds of exceptions. - Modified switching to Dolby Digital audio in live mode, if the driver and firmware can handle live DD without the need of a Transfer Mode (thanks to Werner Fink). Live DD mode requires a full featured DVB card and a LinuxDVB driver with firmware version 0x2622 or higher. Older versions will use Transfer Mode just like before. - Implemented handling of the "CA PMT Reply" for CAMs (thanks to Marco Schlüßler for figuring out some obscure length bytes in the CA PMT Reply data of AlphaCrypt CAMs). - Some preparations for being able to record several encrypted channels from the same transponder at the same time (or record and view different encrypted channels), provided the CAM in use can handle this. This is work in progress and isn't actively used, yet. - Fixed SetProgress() in the 'skincurses' plugin in case Total is 0 (reported by Stefan Huelswitt). - Added a copy constructor to cString and fixed its assignment operator (thanks to Holger Brunn). - The new function Skins.QueueMessage() can be called from a background thread to queue a message for display. See VDR/skins.h for details. - The SVDRP command MESG uses the new message queueing facility, so MESG commands may now be executed at any time, and the message will be displayed (no more "pending message").
