Problems with Sony PXW-FS5 footage

We are using the Sony PXW-FS5 with the XAVC Codec. When exporting with pass-trough settings for video and audio, the files are not longer recognized in Adobe Premiere CC (latest version). We also tried to open the files with Quicktime and VLC player.. no chance to use them. When opening the recorded files directly in Premiere, there are no issues.

So we have to convert all files with the Adobe Media Encoder before synchronizing them in Tentacle Sync Studio.

We have tried it with the latest version of the Tentacle Sync Studio software both with license and with dongle.

By the way: there are absolutely no problems with footage from the Sony PXW-FS7.
