Audio Sync / Quality Problem on render with last two PPA Devel version on Ubuntu 12.04

Howdy all,
I seem to have developed a problem with rendered audio sync / quality.
It developed after I installed the 11_16 PPA Sunab Devel versrion.
Everything audio was working fine before. The problem still seems to exist with the current
11-22 Sunab PPA. Here are links to a couple of short files that show the problem.

I tested the players with other previously rendered files they play fine.
The video seems to render fine on any version previoius to the 11_16 release.
I tried it with a variety of materials and sources. The one above was originally from NTSC DV.
I wonder if this has something to do with Ubuntu switching to avconf and the difference in settings per

I have not tried fooling around with this yet, but I did check the MPEG 2 render settings in the current devel version vs the older working ones and they seem to be the same.

It is possible there is some conflict as I did all the Ubuntu upgrades also with it.
My upgrade history log is hawaiipoliticalreporter.org/video/history.log

I am running Ubuntu 12.04 LTS with 320-33 generic I think 32 bit version.

Let me know any tests, steps, logs that will be helpful. I need to edit a show soon, so I might need to uninstall this and try a previous sunabl version. Any tips on how to get that version ?
He seems to list only the last two (which seem not to work on my machine).

Thanks for your help.
