Landscape vs Potrait

[Guest]

All of a sudden my images are rotating during playback. On the timeline they
are correct but all of a sudden they are rotating to potrait view. It is
quite a large movie any suggestions?

What is the file type?
If it's incompatible you may need to convert it to say wmv to get it to work
properly
