You don't need v27; stick with v28 as it's newest. What you're doing wrong is burning the file to a CD-R. The MDF file is an image of the disc, and the MDS is the file that tells Alcohol about the MDF file. In short, what you need to do is open Alcohol, click Image Burning Wizard on the left, and locate the MDS file. Alcohol will then create the CD from the image. That should work.
When you've successfully updated your firmware, post back and we'll help you enable perspective mode.
