- Re-implemented handling of DVB-S2, which first appeared in version 1.5.14, but was revoked in version 1.5.15 in favor of making a stable version 1.6.0. VDR now requires the "multiproto" DVB driver, e.g. from http://jusst.de/hg/multiproto. Note that the channels.conf file now supports additional parameters, so you may want to make sure you have a backup of this file in case you need to go back to the previous version of VDR! - Fixed displaying transponder data when it is modified (thanks to Reinhard Nissl). - Fixed handling the counter in detection of pre 1.3.19 PS data (thanks to Reinhard Nissl). - Improved logging system time changes to avoid problems on slow systems under heavy load (suggested by Helmut Auer). - Now setting the thread name, so that it can be seen in 'top -H' (thanks to Rolf Ahrenberg). - Fixed initializing the timer's flags in the cTimer copy constructor (thanks to Andreas Mair). - Fixed setting the OSD level in the 'osddemo' example (thanks to Wolfgang Rohdewald). - Increased the time between checking the CAM status to 500ms to avoid problems with some CAMs (reported by Arthur Konovalov).
