- Adapted VDR to the NEWSTRUCT driver. To use the new driver, compile VDR with 'make NEWSTRUCT=1' (thanks to Holger Wächtler for some valuable advice). By default it currently still uses the old driver. - Added some missing #includes (thanks to Martin Hammerschmid). - Changed the log error message "can't record MPEG1!" to "error in data stream!", since the mentioning of MPEG1 has irritated many people. - Consistently using malloc/free and new/delete (thanks to Andreas Schultz). - Temporarily made cDevice::ProvidesCa() virtual (Andreas Schultz needs this in his DXR3 plugin). - cDevice no longer exposes a file handle to cPlayer. A derived cPlayer class can now call DevicePoll() to see whether the replay device is ready for further data. A derived cDevice class must implement Poll() and shall check if any of its file handles is ready for data. - Implemented several replay modes to allow players that play only audio (thanks to Stefan Huelswitt). - Improved cCondVar::Wait() and implemented cCondVar::TimedWait() (thanks to Stefan Huelswitt). - VDR no longer gives up if there is no DVB device. It continues to work if there is at least one device, either a DVB device found by the core VDR code itself, or a device implemented by a plugin.
