I have dual DVI working with Natit Dual 0.02
Internal s-video does NOT work

I purchased one of these adapters and tried it with the dual DVI.

No luck.

The problem I suspect is that some cards only produce DVI-I signals therefore getting a DVI-A is near impossible.

If anyone has this working I would love to know

Interesting. Anyone know of any successes using either GMA900 or ATI X1800 ?

I've got gma 945 , got the cable but it wasn't working...

ok... i have just built a new computer on the p5k-e motherboard with a 2.2 dual core processor and 4gb ram, for graphics i use the geforce 7300gt and my old fx5200 card. Everything workes fine with vanilla kernel and 10.5.2 update but something strange is happening when i try to get the s-video to work. i acctually got it to work in mirror mode with changeable resolution on both my tv and my monitor but when i restart or try to start up with the s-video cord plugged in it all goes bananas!
than i have to remove NVinject witch i used and reinstall the whole thing.. very strange i think.. any1 have any ideas? plz help!

Hi I have a P5K and I have a PCI-E 7800 GTX 512, the same thing happens to me!

I can get TV out by plugging in the s-video plug AFTER starting the osx86, I then have to unplug my monitor, and that forces a picture to my TV, I then plug the monitor back in to the opposite DVI port than before and it works, but as you said it goes mad when I restart.

I'm close to buying some DVI and s-video extension cables so I can do this hacky cable madness without groveling around on the floor, selotape them to the side of my desk or something!

I've tried changing around with my info.plist and I get more or less the same thing happen. (plug tv cable in after, change monitor cable aroun, etc etc. 13 0C works best for me. and yields the results mentioned above. Weird.

Any ideas on why this is?

I wish i had read this topic earlier.

my mediacentre has a GMA 915, and an Asus 7300GS. Native TV-out gave kernel panics so I bought a DVI to S-video converter at the apple store but it doesn't work. I see the bios screen (garbled) and when it should display the apple boot screen it just gives black screen. my video preferences look like this.

and the about window says this:
Attached File  about.tiff   77.75KB   68 downloads

As you can see I cannot switch to PAL/50Hz display. Resolution switching works but it just doesn't give ou tput to the TV, i can control the computer with screensharing so I know the computer hasn't crashed.

@ doobiebro : I think it needs the NVCAP to be edited so that you tell the driver to ouptut TV format to the desired chanel

somebody said that that a switch is activated to change the signal output on ati cards to set it to s-video, which is why it doesnt work with nvidia, but isnt s-video just analog?

if thats the case cant i just use my dvi to vga thing that came with my card, and pick up one of those vga to s-video cables ive seen floating around the internet for $1.99, or would the signal be off? or if dvi-i to s-video doesnt work, would dvi to vga not work under osx? i havent had to use it since my windows only days...

Has anyone tried this on a 2600XT? Apple says it's compatible, I want to be sure before dropping $70 on a card and another $20 on the adapter...
