I see a new build of DVDA Pro 5.2 is out. Hopefully it fixed the problems with build 132. However I will stay with build 124 until I find a compelling reason to change.
BTW, I'm cautiously optimistic. I installed build 133 on top of build 132, and for the first time in weeks, DVDA 5.2 is able to render a Blu-ray project. DVDA 5.0b is also still working.
