Using Resolve 12 Studio and importing a simple time line from Premier Pro 2015 via XML. The timeline seems to re-construct correctly, EXCEPT, the wave forms for the all channels other then the first one do not draw and audio only emits for the first channel. Specifically, the audio that is embedded in the QuickTime (PRHQ) exhibits this behavior. There is a head build with another QT file that is bars with external wave files for the 1K tone ... that part is OK, just the embedded audio from the quicktime that is not correct.
If I send an AAF the main program section looks OK -- that audio routes correctly and the waveform previews draw correctly, but my slate file, bars and tone file are not linked. I know, strange. This is a simple "mastering build" so not even any internal edits. like 3 pieces of media.
