There is currently no api method for turning a Virtual Earth Collection from maps.live.com into a GeoRss file.
However there is a workaround that you can use as follows:
- Open your collection on maps.live.com
- Click the Share button and select either "Send in e-mail" or "Copy to clipboard" - what you want is the URL for the collection
- Visit the URL in the clipboard or the e-mail - it will be something like: http://maps.live.com/?v=2&cid=FB8B852EF1AB0B35!519&encType=1
- When the collection is displayed you will see a Subscribe link at the top of the collection items in the left panel. Click on that to open the GeoRss feed.
- IE will open it and format it, but you can view source or save it to file to get the raw GeoRss data.
With thanks to Derek (MSFT) for originally posting this on the VE Forum back in October last year - I recently needed to do this again, and searched for the comment. I thought a blog post might help people find it more easily in the future...
Cheers

UPDATE: In VE 6.1 this is now a feature of the UI at maps.live.com, just select Export from your collections Action menu - so no need for this procedure any more!
