I have just brought a Sony HDR-PJ200 handycam and I imported the video from the camera to the Playmemories Home installed on my computer and when I click on the edit button to edit my video in Playmemories home the error says unable to perform the selected operation because non of the selected media files are in a file format that supports this feature.
Have you connected the PJ200 to the PC once via USB? To use certain features of the Play Memories software and for support of certain file formats the device has to be connected once to the PC. So if you copy the files from storage card only, the features may not be installed yet. I have checked PlayMemoreis with PJ260 and there was no problem opening/editing the video files.
