I converted avi file to dvd and mov files using ffmpegx... they work in QT and in ffmpeg's mplayer, but I get an error message from popcorn when I try to burn the file, " ... not a valid video image file". The file will drop into iDVD5 but its size is too big for my 4GB disks.

I have tried several smaller avi files with the same result in popcorn. I have searched many sites with no solution.

Thanks for any help.
