AC3-5.1 to AAC-5.1 .... some info header tool?

I used BeLight/BeSweet with Nero6 aac to reencode ac3 audio to aac-5.1. But resulting aac audio file is always without lot of details which is very noticable comparing it to ac3 original no matter if I even use [Transcode] quality option or just [Streaming].

First I thought it was something with nero aac library, but than i transcode it to ogg 5.1 and it gave me totaly wrong channel order center get on left, left on right. So it gave me thought that aac might also produce wrong channel order and that's the reason why i dont hear the same sound from ac3 and aac files.

Is there any tool that could give an info about channel configuration inside the encoded files? So that I can be sure that all channels are in the same order in transcoded file as they're in ac3.

Or is this maybe an decoder that produces the ottputs on the wrong channels?
