Version 0.92vdr-0.92
- The "channel not sync'ed" log message now also lists the card number. - Now using the EIT services from 'libdtv' (thanks to Rolf Hakenes), which provides EPG information for NVOD ("Near Video On Demand") channels. - Doing some bug fixing on the EPG data (some tv stations apparently have their own idea on how to fill in the data...). The level up to which EPG bugs are fixed can be controlled with the EPGBugfixLevel parameter in the "Setup" menu (see MANUAL for details, and cEventInfo::FixEpgBugs() in eit.c for the actual implementation). - Fixed broken recordings after a driver buffer overflow. - Fixed the chirping sound after Pause/Play of a DVD (thanks to Andreas Schultz).
