Regarding gaming and HDTV video/audio lag

I recently upgraded my primary TV and decided it was time to step into the HDTV era and away from my old dinosaur CRT. I decided to pick up the 40" Sony Bravia S5100 (1080p, 60hz) after getting a ridiculously good price match sale from Best Buy.

Upon bringing it home and setting it up, my first instinct was to play some Rock Band 2 in my new HD goodness, but something didn't feel quite right. After reading a few different methods online and taking about an hour and a half to try a few different things, I think I've got it calibrated pretty accurately to account for the video and audio lag that my new tv is suffering (on my old crt I just kept both settings to 0ms.)

After a bit of trial and error, I've got it set to the following:

audio offset: +90ms
video offset: +25ms.

Seems to do the trick for Rock Band, I'm able to play most everything I'd been able to play on my old set comfortably, without any incredibly distracting or obvious lag or error (though I could probably get even more OCD on it, fluctuate either offset by a few ms in either direction, til I have it absolutely, positively perfect. As it stands now though, it'd take being VERY discriminatory to scrutinize it any further.)

If you've read this far, I appreciate your diligence! It's about to pay off, as my main question is this:

Will the lag and offset that I'm experiencing through Rock Band translate to the rest of my XBox 360 games as well? Rock Band has the option to offset the lag (which is great), but for something like Gears of War 2 or Call of Duty 4, games that take very quick reflexes and reaction timing, is the lag between what I'm seeing on screen and what I'm doing on my controller going to put me at a disadvantage?

Even at most the video lag I've experienced in Rock Band is 25ms - 30ms, which is only a fraction of a second at best. Still, I can't help but wonder, in the world of 2-piecing and headshots, if that fraction of a second isn't going to be the difference between me dominating or getting dominated. :P

Any ideas, opinions, or credible information is GREATLY appreciated. :)

Try another game to see this, you should get a plasma instead of and LCD.

Plasmas run the risk of burn-in though, eh? As much as I do love Assassin's Creed, for example, I'd hate to be looking at Altair's ghostly life bar any time I try and watch a movie. :P

Do I know if such a smaller margin will matter in gaming? No I don't. But the lag is because you got a 60 hz rather than a 120 hz ;). And in my experience LCD is better for movies and gaming than plasma. There is a reason it costs more.

I remember reading some where that rock band and guitar hero have video/audio mismatch problems on lcd tvs

I have both and there is no way i use the LCD for gamming, is true you get a little IR when you play a lot with games that have some bars, but generally speaking only high end LCD compare to plasma.

They cost more cause builders want to, LCD are cheapper to build than plasma, builder and seller make more profit from LCD so they push the LCD's to sell more, to get the PQ of a $800 plasma you need to spend about $1200-1300 on a LCD that doesn't make sence ;)
