NTSC streams are not broadcast raw. What do you call encoding data that's already encoded if you don't think it's reencoding? Also, doing so causes degredation so unless there's a need for the user to do so, he's better off not wasting his time. >> Tuners do NOT provide raw audio/video to the system in any case. > > http://corona.homeunix.net/cx88wiki/Overview/RawVideo While that's technically possible in _some_ cases, and assuming it's fully implemented and functional, I'm unaware of any software that actually provides raw data to the user. I suppose I should have worded my point differently.
