Just switched cameras to Panasonic Lumix DMC ZS50 and also upgraded from LR 5 to 6 (and today to 6.4). I can't import .mts files from a memory card or even the hard disc (I copied them to disc and tried importing from there but again LR doesn't see them). I can see and play these files in Windows Media Player. I can also see and play .mts file from my Sony A6000 which I previously imported into LR 5. Is this a known bug? Is there a fix?
