[mythtv] Playback profiles?

[Daniel Thor Kristjansson]

]Something I'm struggling with is the difference in vibrance between
]ATSC and NTSC recordings, and between monitors (DLP vs. LCD vs. CRT,
]in my case).  NTSC recordings at the default PVR input levels look
]very washed-out compared to ATSC recordings of the same material, but
]I can modify the Xv picture settings to compensate for the most part.

]I don't see an easy solution to this.  I think an architecture change

]The playback profile is determined by a tuple (recordid, frontend
]name) so that one can fine-tune specific types of recordings to
]particular frontends.  In my case, a washed out (say) ST:TNG scheduled
]recording will be associated with

I think playback profiles make sense, just make sure that they are easy 
to configure. I would very much like it if deinterlacing was used only 
when playing to progresive scan monitor, or when the resolution was 
different from the source material. Also I don't think I see the washed 
out thing you see with IVTV recordings, maybe we need some kind of 
wizard to set this up. "Does this image look to vibrant or too washed 
out?", "Does this image look too bright, or too dark?", "Does this 
interlaced image flicker, or does it show tearing?", etc.
