I have two problems with Encore right now. The first is that, when I hit "Export to Encore" in Premiere Pro, my system no longer starts Encore. No crashes or anything, but it just doesn't start Encore. The second is that, when I want to import a PP sequence into Encore, I need to select the correct disk directory or folder... and Encore doesn't seem to be able to see into that folder. (It's a subdirectory from "My Videos." It doesn't show me directories under that one.)
What version of PR and EN?
Please post a screenshot of the import window you are describing.
What operating system?
You might try looking at windows event viewer to see whether an error is recorded when you are sending from PR to EN. Look for the faulting module.
