I'm using a couple of MPEG clips, and when I try to use the ripple tool on the timeline, it doesn't show both clips side by side on the Program Monitor, only one. Then if I try to use the ripple tool on the Program monitor, It shows "Media pending".
It doesn't happen with other clips. Is it a problem with codecs or the program?
I'm sorry if it's a noob question but I'm just starting.
