Version 0.91vdr-0.91
- Fixed displaying colored button texts that are too long. - Suppressing replay progress display when replaying a DVD. - Updated channels.conf.cable (thanks to Uwe Scheffler). - Updated French OSD texts (thanks to Jean-Claude Repetto). - Improved AC3 decoding when replaying DVDs (thanks to Matjaz Thaler). - Fixed handling DVB card indexes when using only one card in a multi-card system. - Changed the 'Eject DVD' button text to a simple 'Eject' (the German text was too long...). - Made the font file generation more stable (thanks to Artur Skawina). - Changed the default value for the "DiSEqC" setup parameter to "off". - The new command line option '-E' can be used to define where the EPG data shall be written to. This is especially useful if VDR runs in a system that turns off the video disk when it is not used, and therefore needs to write the EPG file to a ramdisk (or turn off writing it alltogether). See 'vdr --help' for details. - Making sure the disk is up and running before starting recording (this is important for systems that turn off the video disk when it is not used). - Added the "Jump" function in replay mode (thanks to Stefan Huelswitt). See the description of the "Red" key in MANUAL under "Replay Control" for details. - Fixed displaying editing marks when toggling a mark in "pause" mode. - If there is no free DVB device to record, the log message will now be given only once. - Made I/O more robust by handling EINTR (thanks to Werner Fink).
