 VDR Plugin 'streamdev' Revision History
 ---------------------------------------
  
+- analog video channels use the same transponder and pid for different
+  channels, so streamdev-client must always issue TUNE command
 - server must close the VTP connection also if filter stream is broken
 - fixed missing #ifdefs for new NumProvidedSystems setup option
 - new externremux.sh mencoder config options: audio pid by language code
