[mythtv-users] Nvidia TV Encoder not listing any support HD modes

[Justin Nolan]

I'm giving up trying to output 1080i via DVI->HDMI without all types  
of weird judder, so I've turned to tv-out/component video. I've never  
seen any different between Component and DVI on my Sony 1080i RPTV, so  
it shouldn't be any loss. Although I've ran into a major hurdle: I  
can't get any HD resolutions working w/ TV out. My graphics card is a  
XFX 7200GS, and I'm using a nvidia 7-pin HDTV breakout cable plugged  
into the TV out port (gfx card manual says the port supports 4, 7, and  
9 pin cables/adapters).

I'm using the latest driver from nvidia, and my xorg.conf is as such:

> Section "Monitor"
>     Identifier     "Generic Monitor"
>     HorizSync       30.0 - 130.0
>     VertRefresh     50.0 - 160.0
>     Option         "DPMS"
> EndSection
>
> Section "Device"
>     Identifier     "nVidia Corporation G72 [GeForce 7300 SE]"
>     Driver         "nvidia"
> EndSection
>
> Section "Screen"
>     Identifier     "Default Screen"
>     Device         "nVidia Corporation G72 [GeForce 7300 SE]"
>     Monitor        "Generic Monitor"
>     DefaultDepth    24
>     Option         "UseDisplayDevice" "TV"
>     Option         "TVOutFormat" "COMPONENT"
>     Option         "TVStandard" "HD1080i"
>     SubSection     "Display"
>         Depth       24
>         Modes      "1920x1080"
>     EndSubSection
> EndSection

According to the xorg log, it doesn't seem to complain about the  
HD1080i mode. But then:

> (WW) NVIDIA(0): No valid modes for "1920x1080"; removing.
> (WW) NVIDIA(0):
> (WW) NVIDIA(0): Unable to validate any modes; falling back to the  
> default mode
> (WW) NVIDIA(0): "nvidia-auto-select".
> (WW) NVIDIA(0):
> (II) NVIDIA(0): Validated modes:
> (II) NVIDIA(0): "nvidia-auto-select"
> (II) NVIDIA(0): Virtual screen size determined to be 800 x 600


What actually happens on the screen is that for the first few minutes  
its a garbled mess of flickering red lines. After a few minutes the  
screen appears in a small 800x600 window in the center of the screen  
surrounded by black. My tv displays grey bars on the left and right on  
everything except an HD signal. That tells me it actually is receiving  
a 1080i signal, but with only a 800x600 pixel image.

And here's the part that is really making me pull out my hair. The  
nvidia tv encoder on the card isn't reporting any supported HD modes:

> (--) NVIDIA(0): Connected display device(s) on GeForce 7300 SE/7200  
> GS at

What would cause no HDTV modes to be listed? I've been struggling with  
this for going on 8 hours, so any input is much appreciated. Thanks!
