I've used Kunaki for at least a dozen releases. They are the best deal and service I have found short run projects which all of mine are. They are very machine line meaning very unlikely to get actual contact from them if questions but really they have the FAQ and overall experienced so well thought out I can see why. If you follow their graphic dimensions to a tee it all works like a charm. Their concept is you use an off-line builder to bundle all info/audio/graphics to an exe file and then at the end of the process you upload that. The only fly in the ointment is it's a Windows based process for the build and upload, they do not support Mac unfortunately.
