Pro 13 shouldn’t have any problems reading MTS/AVCHD files so there’s something wrong with your machine.
Have you always had this problem or is it only recently that this started happening?
You mentioned downloading codecs and that’s never a good idea as it’s well known that some of them (especially products like the K-Lite codec pack) replace known good codecs with inferior ones.
I hesitate to mention it but the other thing that comes to mind is that if this is a “less than legitimate” copy of Pro 13, then that’s your problem as cracked copies are known to have bugs.
