Do you happen to remember the context of the thread Randy?
It's been a long time, so I don't remember much of it. Someone asked something that seemed completely innocuous, like whether or not a Mac could be set up to play Blu-Ray disks, and I recall that I gave a completely innocuous answer. So it shocked me that I was treated like an outlaw for my answer.
If anyone would tend to be adverse to wading into illegal matters, it would be me. Except possibly to explain why they are illegal.
It would seem to me that this s important. I've always taken the view that discussion of Blu-Ray players (hardware) was legit because a member could use that hardware for legit purposes (such as backing up one's music library). There are some discussions which would likely be shut down quickly such as someone seeking advice on ripping copy-protected content.
If nothing else, Blu-Ray players are legit to play commercial Blu-Ray disks. Just because Apple decided to skip Blu-Ray technology doesn't make it illegal to use with a Mac.
There's nothing wrong with using Blu-Ray as a backup medium per se. The law makes it legal to rip one backup of a legitimately purchased copyrighted copy of digital material, but the DMCA arguably makes that single legal backup illegal if one has to defeat copy protection to do it. So it is likely not legal to use Blu-Ray to backup your Blu-Ray disks, but it should be fine to use Blu-Ray as a long term backup medium for downloaded material with or without copy protection as long as you are not defeating the copyright protection in the process.
