I did my free upgrade to Windows 10 last week. Noticed yesterday that when I put in my memory card to move my AHDC .mts video files over, nothing will play or open them now. I tried Windows Media Player, Windows Movie Maker, Adobe Premiere and VLC player, but nothing works!
I was liking Windows 10 until this. No I'm mad, frustrated and depressed that I even upgraded.
Please, anyone help without having to try and roll-back to Windows 8!
