Yes, I have seen Tony's tutorial and a few others. I get no error. I export a simple 20 second flash from cs4 to mov.
Export>mov animation setting, keep the same size.
The bar goes through what looks like it's exporting and stays there. NO ERROR EVER
But check and there is no mov. And also I have tried it ten times and it never asks if I want to write over the last so it is not hidden or anything, it just never exports.
The only script is to stop at the end.
There is no option to just publish to mov either.
Thanks for that one - I was having the exact same problem.
I'm building a showreel that includes some Flash projects. Reworking old Flash files to get rid of Actionscript and nested clips is a bit tedious, but much better than tearing my hair out wondering why it wouldn't export to MOV.
