Many thanks for all those interesting answers.
Talking about SBD audio, audio guy from Texola provided me of a saturated, overloaded SBD audio. He capture it with his laptop with an audio card... I have no more info at this momment.
You can check SBD on this video, before a little "remastering" (if I can use this word for volume adjustment, levelling, balance....):

You can listen totally not ballanced guitars ("red guitar" sound higher than "lead black guitar").. but it's a clean SBD.
When I matrix this SBD, with an AUD, I must correct speed to sync... not to much, sounds like this:

Next sample was taped with Zoom H2 fixed on SBD, 1 meter higher than audience, more or less in fron of stage about 20meters long, in an open air auditorium with 3.000 people atendance:

DORO:
http://www.youtube.com/watch?v=now9i2gzd3AI was reading this excellent forum to know how to get the best from my Zoom H2.
With all this samples, maybe my last 7 months short taper life is covered, (when I started with this Zoom H2). I must admit that for an used gear ... my Zoom H2 did a real good job.
For sure talking here about Zoom H2 it's a very good gear it's like talk about iphone is a very good photocam... but my experience is that is a good point to start taping with a very low cost.
So I'll go for sure to a CA BateryBox+CA14 cardioids, to try to upgrade all these, maybe new upgraded CA-11 cardioids will be welcome too (I think Chris Church tal about this somehre here in the forum).
As Acidjack pointed, with external mics, stereo must be more better than a fixed internal mics.... and this is an important thing I want to get on my next recordings.
I'll ask Chris Church... but if someone want to sell his used gear for a major upgrade, please PM me (I will write a post on yard sale too)
