export to wmv

i have quicktime pro and the flip4mac wmv plug in. when i use quicktime pro to export a file to wmv it only does the first 30 seconds or so. then it just finishes as if that was the whole file. i have the entire video selected on the bar but it doesnt make a difference. whats happening?

You have to upgrade to Flip4Mac studio
