Interesting. My understanding of AVCHD was that it was an HD video standard developed by Sony that uses the H.264 codec and is fully compatible with the Blu-Ray disc format. So, if I have an AVCHD file structure, wouldn't it just be a matter of burning this to a blank BD with BD authoring software? That's my definition of trivial!

Again, terminology. AVCHD when describing a disc layout is as you stated. AVCHD when talking about the disc itself (particularly a DeEd disc, which has been distributed in this form before) is as I stated. Which is why it's best to not use the word unless you're careful to specify what you mean.

As long as you create the right Blu-ray folder structure for a Blu-ray (just an option in tsmuxer), yeah, just burn the folders to disc and be happy. I downloaded the MKV and maybe 30 minutes later had a working Blu-ray. It is definitely trivial.
