I used to be able to import .mts files. I did have some problems with exporting the files, but I could preview them and work with them. I was working in a AVCHD 1080i 25fps sequence, with 48 Khz, audio. Now when I try to open a new sequence, I can’t choose AVCHD and when I try to import .mts, it says the file format is not supported. This update was suggested by the updater.
