Yes, that should work.
I don't play Counter-Strike. I am not any good at first person shooters. I tend to prefer old Nintendo and DOS games.

Probably. I have never used DVI and the software is different for every video card, so I don't know how to set it up.
My guess is that you should go to Control Panel -> Display -> Settings tab -> Advanced and look for a setting there that allows you to switch the DVI output on. If your video card came with any applications, you might check there too.

Hhmm. I did a bit more web searching and found that some TVs use HDCP (High-bandwidth Digital Copy Protection), which makes it incompatible with video cards that don't support it. You might check to see if your TV has that.
Another possibility is that your TV only supports certain resolutions and refresh rates. Check your TV's manual. If you can't find that information in the manual, then you could try different combinations of settings and see if they work, but it might be possible to damage your TV by trying to use it with an unsupported resolution or refresh rate (though I'm not sure why it would).

hey you people wouldnt know how to convert an svideo cable to composite? i have modified 2 ps2 mouse cables into svideo cables and they work fine..but i need to know how to make it composite without buying an adapter

You convert S-video (seperate video) into composite video by amplitude modulating the two chrominance signals in quadriture on a 3.579545 MHz subcarrier and adding it to the luminance signal, and then adding 8-10 cycles of the subcarrier after each horizontal sync pulse.
In other words, you would have to be an electrical engineer to do it yourself, and buying a single set of parts to build your own converter, which probably wouldn't work on the first try, might cost more than buying a mass-produced converter.

nope..did it faster than i thought it would take...there are only 2 main outputs on the svideo cable..the other 2 are for clarification..in other words..to sharpen the picture..but the 2 main connectors i hace found out are the top 2 pins one on each side the 2 below those are the "extra" output i am actually running on my tv with my homemade s-video/composite adapter as i am typing this message..go computer knowledge!

I read up on S-video a bit more, and it turns out you did a neat trick even though you have no clue what you are talking about.
To produce color video in the line by line format that TVs use, you need three signals. For computer monitors, those signals are commonly red, green, and blue. For TVs, those signals are commonly luminance and two chrominance signals.
The electrical engineers who designed color television found a neat way to jam the three signals (and an audio signal) into one signal in such a way that it was still compatible with black and white televisions and still fit within the 6 MHz bandwidth already assigned to TV channels. That jammed together signal (without the audio) is called composite video for that reason.
I had wrongly assumed that S-video separated the video into luminance and two separate chrominance signals on three different pins and that the third pin was ground. Actually, it separates the luminance signal, but keeps the chrominance signals modulated together in quadrature at the same subcarrier. The other two pins are separate grounds for each of those two signals. Giving the two analog signals separate ground wires reduces noise and separating the chrominance from luminance means a low-pass filter is no longer required to separate the two signals internally. Applying a low-pass filter to a signal makes it fuzzier.
Since the chrominance signals are still modulated together, you don't have to do any modulation to convert the signal as I thought. You actually just have to add the signals using an analog adder. What you did was an interesting trick. You plugged the luminance signal into the composite in, but instead of plugging the luminance ground into ground, which would have given you the black and white image, you plugged the chrominance signal into ground. That way, an increase in the voltage on the chrominace line would cause less voltage between composite in and ground and vice versa. In other words, you effectively subtracted the chrominance signal from the luminance signal instead of adding it. That means the chrominance portion is 180 degrees out of phase, but because of the phase relative nature of the chrominance signal, it produces the same image.

I'm having a slight problem and this is the right titles thread, if the original poster doesn't mind me adding it here.
I was wondering if upgrading from my current gforce FX 5200 to a ati 9800 pro would give me better resolution through the tv?

actually changing video card wont make much of a difference..if you have the nvidia card presently try using the clone option under nview options so you use your desktop on the tv..for movies...etc
