Thanks Stinky- that helped.
Imgburn was able to to burn the files, but I got thousands of failures during the verification step. I clicked <Continue> long enough that it just kept going, logging each error as it went. It got held up at 90%, as every sector was having a problem at that point, and so I just cancelled the whole thing and ejected the disk. Funny thing, it played just fine on my PS3, which was fanastic!
Now....ESB and ROTJ....here I come
thanks again
