Looking to buy a TV card and am totally clueless...help

A TV tuner card allow you to input TV cable and composite video to view or save them in your computer. If all you want to do is to playback your divx movies from your computer to your tv, then all you need is a video card with a TV out, either composite or svhs. most recent video card has it. look at yours and you maybe already have all than you need.

Remote control can be bought separatly, like the own Microsoft one,for about 30$

You don't understand. The connector on the video card is only for OUTPUT. it means that you can use your TV to see what your computer output. If you want to watch movie from your DVD player to your computer screen, then you need an INPUT card.

From your first post, it seems that you want to use your TV for watching video that you have on your computer. For that, the OUTPUT on the video card should be plugged to an INPUT on the TV set or a VCR... And TV should be activated in the video settings.

So, what do you want to do exactly?

I know, but he don't seem to know...He said he wanted to watch his video from the computer on the TV, but try to hook the video card to a DVD player...

You already have the card. all you need is a svideo to composite converter. most video card use one, instad of having to put 2 output on the card. Then you nne to send the sound out to tv, which is done by connecting a wire between the speaker port on the computer(usually the green hole) to the audio connector on the TV. wire that have the 1/8 plug for the computer and RCA jack for the tv can be bought at electronic store.

ATI cards support Composite video, your card should have included an adapter cable. Not a signal coverter, such as you'd buy from Radio Shack, but a simple break-out cable.

It's better to start with a composite signal in the first place, rather than use a signal converter. But if you have no other choice, a signal converter will usually do the job.
