Picture is too bright with DXV codec...

Hi folks, I have strange problem with DXV codec.
I try to convert some MOV photo-jpeg clips in to DXV, and output clips are very bright revalite to original.
I've tried Compressor, Adobe Media Encoder and QuickTime 7, but the result is the same.
I don't know what to do with that...

Here you can see the screenshots:

I suppose the problems is in QuickTime 7 Pro (version 7.6.3 (630)).
It plays video (even original photo-jpeg files!) much brighter and sometimes with wrong colors!
QuickTimeX and VLC don't have this problem.
But why? And how to solve this problem?
I run Mac OS X 10.6.2...

But nevertheless, video in DXV is extremely bright. Much more brighter then for example in PNG or Animation codec…
The problem is not only in QuickTime 7.

Yes we know it alters the colours slightly but can you email those two clips to us on
mail@resolume.com so we can have a look? Perhaps you found an extreme case.
A quick and dirty solution would be to put the Brigtness Contrast plugin on the composition and adjust it slightly to make it darker.

Thanks for sending the files, it's subtle but there is indeed a difference. Perhaps we can fix this in the next version of the DXV codec.
For now I suggest using the Brightness Contrast effect or the Exposure effect to make it a bit darker.

Thank you.
And what can you say about QuickTime 7 Pro brightness? Do you have the same problem?
