VDR Plugin 'streamdev' Revision History
---------------------------------------
- now there's a common baseclass for all remuxers, make use of it
- added cDevice::NumProvidedSystems() which was introduced in VDR 1.7.0
- added namespace to remuxers
- increased WRITERBUFSIZE - buffer was too small for high bandwidth content
