place on the web to find optical media companies in central america?

Huh? Luis, what in the world does this have to do with home theater ELECTRONICS? I think maybe you wandered into the wrong forum. Here, we discuss questions mostly relating to home theater system and TV operational and electronics questions. Maybe the Business & Finance forum? And the vast majority here live in the USA and have no personal knowledge of what's happening in Central America.

I don't think this technology is available in Central America. That's why you can't find it.
