- Improved responsiveness inside CAM menus. - Added handling of the 'Close MMI' tag to avoid error log messages with CAMs that actually use it. - Now waiting at startup until all DVB devices are ready. This includes having all CAMs initialized and ready to decrypt, so that no more "channel not available" happens if VDR is started with the current channel being an encrypted one, or a timer on such a channel hits right after starting VDR. - Fixed cVideoRepacker to better handle errors in data (thanks to Reinhard Nissl). - Fixed cDvbTuner to avoid lockups on NPTL systems (thanks to Marcel Wiesweg). - Added 'Service' functions to the plugin interface (thanks to Udo Richter). See PLUGINS.html, section "Custom services" for details. - Replaced the get/put_unaligned() macros from <asm/unaligned.h> with own inline functions to avoid problems on platforms that don't provide these (thanks to David Woodhouse for his help).
