Again, using another's settings may not work well at all because of component tolerance differences and your viewing environment. However, if you understand that, and don't freak out if your tv looks worse, and you think you have a bad tv, that's fine as a starting point. I've seen people post back worrying that they've screwed up their tv, or something is wrong with their tv because a "killer" set of cal settings looks like crap on their set. I've even seen folks get into the service menu to "correct" the settings and really mess things up. OTOH, I've seen people use someone else's settings and be totally happy with them. So a little knowledge of what is happening can go a long way in eliminating unnecessary stress. And it doesn't matter at all if the borrowed settings were done with meters or not because the underlying principle is still the same. No two tv's are exactly the same, even within the same model line or build sequence, so calibrating is setting your components to match rec.709 standards in your viewing environment. Quite often, just properly using a disk is all that some need to achieve what they feel looks great to them.
