Hello Gerry,
Hey I’ve had the “from what i can see” exact same problem.
I edit in the Native format, Import the way adobe recommends too from the sxs cards.
I was paranoid that the camera was corrupting the files when i managed to get hold of a mac and use FCP where they played fine. As this is the ONLY relevant forum i have found and numerous calls to customer support have not and trolling through various forums enlightened me.
would you or anyone have the slightest inclination as to where the origins of this issue stem from.
I have been tossing up missing codecs?
Thanking you
Kate
