about "Getting started" in PLUGINS.html and adapt their code if applicable.
- Implemented the CableDeliverySystemDescriptor in libdtv (thanks to Sven Grothklags)
- Implemented the CableDeliverySystemDescriptor and TerrestrialDeliverySystemDescriptor
in libdtv (thanks to Sven Grothklags and Andreas Schultz)
- Fixed keeping live video active in case the primary device doesn't have an MPEG
decoder (thanks to Wolfgang Goeller for reporting this one).
- Implemented cDevice::ActualDevice(), which returns the actual receiving device in
