Hi,
I've been following this list for sometime now, paying particular
attention to those who are capturing/outputting HD
I've seen a lot of posts from poeple telling others to turn on the
deinterlacer, or that playback is better with the deinterlacer on. Given that the modelines I've seen are set to output 720p or 1080i,
what are we deinterlacing for?
Assuming that the TV supports inputs of 720p and 1080i, can't the
original format just be passed straight to the TV?
My thinking is (and I'm probably way off :) ) if the TV has a ATSC
tuner, and both 1080i and 720p pictures look "as expected", there
should be no loss in quality when feeding a 1080i or 720p input from a
vieo card.
What am I missing here?
This *should* in fact work just fine. Since 6111, nVidia drivers are capable of outputting interlaced modes. Two problems:
* the minute you press that "W" button to scale vertically, your interlaced lines no longer line up.
* I'm not convinced the nVidia Xv overlay is doing the right thing when presented with interlaced video on interlaced output; it's hard to tell, but I think it may be doing onefield deinterlacing, or something approaching linearblend. Pausing some high-motion scene does not produce flicker as it should. Normal (non-Xv) content seems to be working fine, so it's gotta be some bug in the driver... if only we could see the source :-(

Many HDTVs only take 1080i. If they do take both, you would need Myth to switch to different modes depending on the recording being played. I don't know if it is smart enough to do that.
This has worked for a while. Settings->Appearance; 3rd screen or so, "Separate video modes for GUI and TV playback." There's only room for 2 video modes here (plus a GUI mode) but IIRC you can enter more into the database manually.
