Why doesn’t Premier Pro CS6 accept m2P videos?

I have an m2P video that I can import directly into Premier Pro CS4 with no problem and work on but when I import it into Premier Pro CS6 I get the error:

 

                             “There was an error decompressing audio or video”

 

I’ve tried changing the extension  to mp2 and mpg but the result is the same.  I’ve tried converting the file to mpg with TMPGE, excluding the audio, and the result is still the same.  There seems to be something is some header that stops Premier Pro CS6 from accepting this file. Another m2P video I have behaves the same way.

 

Does anyone know what this might be or how I can find it? 

 

Thanks

Steve
