Can't get burn to work for boot or game

[zombieman69]

Additional info: followed steps in post about Utopia loader (before I posted first time), also didn't work. Am wondering if my burner can't do the job. I can burn pc games fine using Nero and .avi and .mpeg files fine with Explorer with this burner, have had no problems until trying this dreamcast stuff. I see this forum and tutorials and links are kinda old, is it still relevant?
