Welcome to the forum mate,

Glad to be of help.

I normally use a cd-r using Imgburn and (touch wood) i've never had a failure.

I always write at x1 speed, (it takes a little longer, but who cares right).

You can write an OS disc with a dvd, handy if the cd head has packed up, but the cd head should read the update disc OK.

Now would be a good time to have a custom setup, have a look at what I've got, http://www.xoutpost.com/305946-post155.html

Hope this helps

John
