Previews and unpredictable audio quality issues?

[rlmbluray]

I have mixed emotions about all the previews on the Blu-ray disks. I think they show you a little too much of the movie they are selling, as well as too many previews before the main feature.

I just installed a Blu-ray player and I am using the 5.1 analog jacks for the best audio.

I thought something was wrong with my system when playing the previews on the Blu-ray disk "Gone Baby Gone". On "Becoming Jane" sound was only coming from the right, and center speakers. The other previews same thing audio coming from different channels with no predictability. However, the preview of "No Country for Old Men" all the analog channels were on.

What's going on with these disks. Why is the audio so messy on the previews? You would think that for the cost the entire DVD would be fully spec'ed.
