Some time ago, I downloaded the firmware update from the Denon site, but never did anything with it. I read the instructions that came in the file and found that the Roxio version 7 that I have did not have the EXACT options that were called out in the instructions (Level 1 ROM disc). It does have the ISO format called out. Not wanting to risk damage to the machine, I never updated.
Now that I will finally be using the hdmi, I figured time to get it done. I sent email to Denon explaining as I just did here and asked if they could send me discs. To my surprise (and disappointment) the reply came "if you can burn a data disc, no problem". If this is the case, what was up with the detailed instructions?

Beyond that, Denon can't afford to send a couple bucks worth of disc out to a customer?
In any case, does it sound safe to do what they now say is okay?
Thanks.
