Exporting to WMV

Hi All,

I've been trying to export my timeline to WMV.

My timeline is 3 minutes 20 seconds in duration but the export only gives me the first 29 seconds of the clip.

My sequence is 960x720 DVCPRO HD 720p50 25fps.

I'm exporting using Export to Quicktime Conversion and I've chosen Windows Media from the list and selected 640x360 frame size. I've tried a variety of bit rates and pre-sets but it's still just encoding the first 29 seconds every time.

All other formats work just fine. I don't have In and Out points set, but I did export a version with In and Out points set at the beginning and end but it made no difference.

I'd appreciate any advice about where I'm going wrong.

Many thanks,

Steve.
