I'm not a technical person so please....

I recently bought an Xtreamer Sidewider 3 which has an HDMI out. My TV is only a CRT, but can run High Definition resolution (may be up to 720p).

While I was roaming around, I saw an hdmi to ypbpr cable for PS3. I was about to buy it thinking that I could use it for the above (my NMT and my CRT TV), but the sales personnel told me that the HDMI part of the cable works only for PS3 and not with NMT...

By the way, my CRT TV has a slot for red, green and blue cables, and I am currently using it to connect to my nmt which has a slot for red, green and blue cables.

I do not have a PS3....

My question is was the sales personnel correct that I could not use the hdmi to ypbpr cable for PS3 to my NMT and CRT TV? tia
