Hi All,
I'm out on office on vacation but I've asked a few colleague to keep the investigation going. The files you provided imported fine into Premiere for me. Can you please try this workaround posted on another thread which seemed to resolve this issue for other users:
"Try renaming or moving the folder with the media. Then open the project in CC 2014. It will ask you where the media is, point it to the renamed or moved folder."
MTS files not importing in Premiere CC 2014
Sorry for the hassle. I will follow up once I return.
