I have LR5.6; I thought is supported AVCHD/.mts videos but it won't recognize those on a memory card. Used Sony DSC-RX100 for these. Tried also by making sure subfolders show, but I can't even find the .mts files in any of the folders. I have the videos on Win Media Player and tried to drag them into a folder in LR but this didn't work. Any suggestions?? Tx!
