Question : Problem: ok i got the new video card, so do i need to use HD cables or S-Video?

ok i got the new card today  SAPPHIRE 100245L radeon hd 4850 512mb

do i need to buy some cables for the HDTV like the green,red,and blue ones? or do i just go s-video to s-video? the card comes with the converter that has a s-video that goes into the card and then converts to Y,Pb, and Pr, but my TV has both, s-video and the Y,Pb,Pr, so i will need to buy some cables to reach the TV since they're both female as well....or will it still be HD with the S-video? i hope i don't sound too stupid lol....i am just new to the HDTV scene, like i said before i know my share about computers in general, but all this other stuff is new to me....Thanks Guys.

well for now,  i extended my display onto the TV, then i swapped displays (maintaining per-display mode settings) and it looks great, i can go to hulu, and other websites with video, or play movies from the HD and full screen them, looks just like i was watching them on TV, and i figured that Callandor but i dont have that many RCA's available that would be long enough so i got these:

they were only $15 bucks. but thanks for everyone's input, next weekend i am going to try and go get the HD DVR from my cable company and they assured me there was an optical Sp/DiF audio out on the box, if that's the case, then i am in business. everything will be connected and work as 1 complete unit, TV, Stereo (and components) and PC, and i am pretty happy with the Video Card so far, i got the best price on MWAVE.com. i think it was $129.99 so until something else stumps me i am Good!

Thanks Again,
