Is all of X black and white? If so, don't over look the
possibility of a bad cable or loose connector.

If just the TV picture is black and white, I've seen this
when the fine tuning of the capture card was off because
the tuner type was not detected correctly for the bttv
driver.

That could do a good job at lower resolutions. Most CPUs
over 1GHz have a good chance of keeping up with 640x480
mpeg4. I recommend the AMD Duron 1.2 or 1.3GHz. They're
dirt cheap, run relatively cool and I know for a fact can
keep up at even 720x480 mpeg4. However, I'd guess that
you'd probably need a new motherboard for one of these.

Hi,
The only other thing that I can think of is that perhaps the output is does
not match the standard for your equipment (PAL/NTSC)?
Often if I get transmission standard in the capture settings wrong, I find
that the pic is sort of OK, but no colour.
Not sure if your TV out has PAL/NTSC output options. Don't have a TVOut card
myself...
Just a thought...

Regard,
Ralph

I have tv out working under Mandrake 9.0, but the image is in black and
white. I am using an old Diamond Viper 550 card. I have see others on the
lists say they are using it, so I am fairly sure I should be able to get it
working.

I have this issue as well. If video is coming off the Television input
of my tuner card (ATI Wonder TV VE), the image is b&w. However, if I
select the Composite1 input (hitting "c" in mythtv), the signal comes in
full color.

For testing I have an antenna hooked up to a VCR, then from the VCR I
have both coax and an RCA composite running to the tuner card. The
signal over the coax seems to be interpreted as b&w, but the composite
is color and looks just fine.

It behaves the same way in XawTV, so it's not a MythTV issue, but
probably a card driver issue.

Svideo out, but using Composite adapter. My video-out does this too
but, only if I munge the nvtv settings. Check in nvtv and adjust your
settings.

Ok, I got color with nvtv. Is there a way to get this to save or recorrect
automatically on boot? I am having to run it everytime I restart. It
shouldn't be a big deal once I get my setup working without problem (Still
having schedualing problems, which I posted about in another thread). It
would be nice to not have to set it up every time though.

Thank you for the help Ralph

nvtv can be run from the command line with no gui. Add it to your
X startup. I added it to .xinitrc for root (since I'm running myth
as root).

I assume that you you couldn't use the same nvtv fix that
solved this for Baba.

There's no fine tuning needed for the composite input which
makes me suspect even more that this is the problem.

Try running xawtv and press the right or left arrow keys
several times to see if that fixes it. If so look through
the archive for messages about tuner type for this card.
