I just installed Movie Edit Pro Plus 2015 and I've been using the 2013 for a few years. I don't have any problem importing M4V files in older versions but in 2015 is says the file cannont be read (see image for error). This is happening with all M4V files (I tried import 3 different files - all had the same error).
However, I can import and edit the file just fine in 2013. Any reason why I get this error in 2015?
