- Added 'Hrvatska radiotelevizija' and 'RTV Slovenija' to ca.conf (thanks to
Paul Gohn).
- Implemented actual user input for CAM enquiry menus.
- Since disk file systems apparently don't honor the O_NONBLOCK flag to read from
a file in non-blocking mode the cDvbPlayer now uses a non blocking file reader
class to make sure replay remains smooth even under heavy system load.
- Increased the maximum possible packet size in remux.c to avoid corrupted streams
with broadcasters that send extremely large PES packets (thanks to Teemu Rantanen).
- Added TS error checking to remux.c (thanks to Teemu Rantanen).
- Modified cRingBufferLinear to avoid excessive memmove() calls in 'Transfer Mode'
and during recordings, which dramatically reduces CPU load. Thanks to Teemu
Rantanen for pinpointing the problem with the excessive memmove() calls.
- Updated 'channels.conf' (thanks to Achim Lange).
- Added/improved Swedish language texts (thanks to Jan Ekholm).
- Fixed the description of the "Scroll pages" OSD setup parameter ('yes' and 'no'
were mixed up).
- Fixed handling the LOG_LOCALn parameters in the -l option (thanks to Dimitrios
Dimitrakos).
- Changed EIT processing to always read a full section.
- Fixed handling user defined CFLAGS in libdtv/libvdr/Makefile (thanks to Clemens
Kirchgatterer and Robert Schiele).
- Fixed skipping unavailable channels in the EPG scanner.
