Fallback provides wrong URL

Using Zencoder/Amazon S3

Works fine in Firefox, Safari, iOS...

However for Internet Explorer 8, which relies on the flash fallback, the wrong URL is provided. It looks like it is putting the amazon s3 url right after the local url.

This causes a 200, Stream not found, NetStream.Play.StreamNotFound, clip... error

View source provides the following:
