[mythtv-users] X output to TV not working?

[Timothy Vann]

I just went through this with my GForce4MX.  Turns out with NVIDIA you have
to enable the driver to do TV-OUT, not sure if your card needs similar
additions to the XF86Config-4 file.  The one thing this driver allows you to
do is to specify a different set of sync rates for the TV-OUT.  TVs can only
run at 30-60 Horizontal sync and 60 Vertical sync(as best as I remember).
You may have some luck by changing your monitor setup section to crank down
the sync rates, but I expect you need a driver that will enable this sort of
dual sync rates.

Short story: TV Out works during bootup (Redhat 9 install), service
startup, console login.  When I startx, the screen goes completely white,
and doesn't work.  What settings do I need in X for proper TV display?

Long story:

Redhat 9 install
XFree86 4.3.0
KDE

I have what may be a not so normal setup in that I'm not actually using
MythTV for a PVR, but rather using it as a (very) pretty interface to
display options for playing my mpg movie collection, mp3s, and easy access
to xmame, etc..

because of this, I am not using a tv tuner card, but rather using a simple
little PCI ATI Rage II+DVD that has svideo out.  I've been
installing/configuring this PC on a real monitor, and when I went to boot
it on the TV yesterday I had interesting results...

During the bootup sequence I received perfect output to my TV, I can
login, etc but as soon as X tries to start, it craps out.  I moved the PC
back over to the monitor, and remembered that I had the resolution at
800x600, so i dropped that back down to 640x480, but I did leave the color
depth at 'millions of colors' (is that problematic with tv's?).  Took it
back over to the television with the same results.  I've read somethin
about X needing to be set at 16bpp (what exactly is bpp?)... I checked my
options from XFree86 -help, and saw that there is a -pixmap24 which is
supposed to "use 24bpp pixmaps for depth 24", but there is nothing for
16..

Is there something simple that I'm missing here?  Or is it the color
depth? (sorry, im running off to work, so i dont have time to check yet)

I'd imagine I'm just missing something silly, or at least thats what I
hope ;)  Thanks to all of you who continue to help us new folks, it's a
very generous way of you to spend your free time.
