Exort video bug with line styles

[Swsubs]

I have a drawing with dash lines inside symbols that appear solid in exported MP4 movies.  Objects with dash lines that aren't in symbols are ok.  WTF?

all your symbols are graphic objects (and not movieclips or buttons)?

Did you scale the symbols that the strokes are inside? I wonder if they have been scaled dramtically and that's the reason the export is breaking them. Click on a symbol containing a stroke in question, open the Transform panel and let us know what the scale percentage is.
