I recently had a lengthy exchange on DReplay with Jonathan Kehayias (SQL MVP). From this exchange I filed several work items with the SQL Server development team to help install and setup DReplay easier in the future.
Jonathan has started a series of blog posts on his experiences that I would only be copying to place on this blog. I suggest you read his series to assist you with your DReplay activities as well.
