S-Video to RCA - color loss?

[mixedup]

Hi all,

I was just connecting the S-Video (TV) output of my graphics card to a TV I have which has a RCA video input (i.e. yellow RCA connected). I'm seeing the picture however it is in Black & White. I've tried various line format settings etc. I am using an S-Video to RCA (Yellow, Red/White) cable that came with the graphics card.

Is there a general color issue trying to go from a recent graphics card (S-Video) output to an older TV RCA (yellow connector) input do you know?

If yes is there a way around this?

Cheers

generally s-vid shouldn't be able to plug into RCA using just a cable - normally some sort of converter is needed.
I'm guessing that actually your graphics card has an s-vid+RCA output - e.g. the connector on the card is not a 'normal' 4pin s-vid connector, but a dual purpose 5 or 6 pin combination connector.
Check the socket on your card - if i'm right and it does have more than 4 pins, then there's probably some configuration option in the software for the card to select between RCA and svhs.

****edit****
it also seems that it could still be a 4pin socket, but you switch which pins do what in the software (i.e. the graphics card options). read this...

You can also make sure you putting the correct format out to the TV.
I usually get a b&K picture on my NTSC TV if the video card is throwing PAL format at the TV.

Also another one that catches people (well it caught me and I'm perfect ) - In the TV out settings of Nvidia cards you can select Composite or SVideo - I figured "My card only has Svideo so I'll select that" - But in fact you need to set it to composite so it formats the signal correctly on the pinouts that the Svideo->Composite(RCA) cable uses. I imagine it could be similar for ATI cards too but its definately in the Nvidia settings.

also thre *are* generic svideo to composite adapters outthere that don't require any special circuits on host, but they don't look so good as a real composite out...funny thing is,they convert comp to svideo rather well..
[it's just a couple of diodes inside connector]
oh and my nvidia card has both with only 4 pins...so doesn't always need 5 pins

Ummm...perhaps this is what caught me out, thanks. I'll try this this evening.

Got some color happening in the end via mixing in the RED as well as the GREEN signal, with the card set of S-Video (c.f. component). So what I have is:
* Video card (WinFast PX7900 GT TDH)
=> output on phyiscal S-video connector on card
=> video driver software is set to "S-Video" & PAL-B
* Plug in cable that came with card i.e. S-Video <==> Red/Green/Black RCAs
* Initially I had the GREEN output feeding the normal Yellow-RCA video input on the older TV => BLACK & WHITE
* Instead go GREEN + RED into the Yellow-RCA input
* May not be perfect as the suggested approach for this included a capacitor etc.

Couldn't quite find a way to get colour an other way with vidoe card software settings (i.e. using NVIDIA control panel. A link to my card details/spec - http://www.leadtek.com/3d_graphic/winfas...tdh_1.html

dude! that's a component video out! lol [notice 3 outs?] i think..
while it will work combining them for composite, it might burn out down the road.. if you have hi def tv then plug them into the component ins..
but hey,if it works for you...

don't have a HD TV, but do have a CRT with S-Video/Component in, however at this stage I have my remote TV sender which has only 1 RCA in/out (i.e. transmits Video from study to TV - cabling is problematic where I am)

BTW - I've just done some testing for full length shows and have discovered it's not just Channel 9 that is having the problem. I've found
- other channel may have the problem whereby recording actually stopped a number of minutes in, also
- I found I had some recordings which recorded the whole show but whereby when playing it back and hitting forward it freezes and doesn't keep playing (i.e. the video freezes, not GB-PVR). After it gets in this state using forward and rewind doesn't help, but you have to go back to the GB-PVR menus
