When i open up a mpg into tmpg to try to cut it into two sections, After I have the first section selected I exit the edit window and then the program crashes with an error. I have followed all the step in the guide to the letter but nothing seems to be working. I have even tried two different versions of tmpg but both do the same thing. I have even tried different files but all do the same thing. Are there any other ways of doing this or am I doing something wrong?
