TVs, usually lower end flatscreen LCDs have a pretty high input lag AND response time compared to PC monitors.
Response time does not equal input lag. Response time is the LCD's ability to change from black, to white, to black again (or grey to grey). Higher response times causes things like ghosting.
Input lag is how long it takes for the TV to display an image after given info about it. TVs usually process the image before you see it. Examples are sharpening, color, 120hz conversion, smoothing, etc. This processing usually contributes to input lag.
When you combine high response time with high input lag, the game feels laggy and unresponsive. This is why some competitive FPS players (and even competitive Super Smash Bros players) like playing on CRT TVs or CRT monitors because they exhibit really low input lag and response times compared to even the highest end flat screen TVs.
Luckily, on a lot of TVs, there is a "Game Mode" that you can activate to lower the input lag by skipping the processing of the image the TV has to do. I use it when playing Gran Turismo 5, and it works pretty well.
Hell my Panasonic 32" LCD TV (TC-L32U3) doesn't even list the response time in its specs, but there is a "Game Mode" in there and it's perceptibly better playing with that on than with it off.
I don't think you need to worry about the apparent lag you see. It's probably attributed to the TV and I doubt it was put in a "Game Mode" that is used to lower input lag for playing games and such.
Though if you really want to make sure the massive input lag isn't coming from the game, test it on a high end PC monitor with very little input lag and response time. Also test with V-sync off and use a powerful single GPU (more info about input lag in this article: http://www.anandtech.com/show/2803)
