From what I understand, BDAV is just a simple playback method and BDMV is the only way to author with menus etc, is this correct?
Also, under what circumstances can m2t files (native HDV) be used as compliant?

Your assessment is correct. BDMV = True Blu authoring. BDAV = HD video on a disc.
Also, I am not an expert in BDAV, but my understanding is the the maximum bit rate is 15mbs as opposed to 40mbs for BDMV. So while you might be able to do justice to 720p in BDAV, 1080p which really should have an MPEG-2 bitrate of at least 24mbs would be a stretch.
I can't comment on the HDV. I don't think that works in BDMV.
Something else to be aware of. Different settops have differing levels of support at this time. Panasonic and 1st gen Samsung player support BDMV on BD-R. First gen Samsung's don't support BDAV, firmware updated Samsung's don't support BDMV on BD-R. You'll have to check the status of other machines support.
Of course this will all even out over time, but in these early days, the status is not too different from that of DVD ten years ago when there was spotty support for DVD-R.

Hi Scott.
Do you happen to know the firmware version of the Samsung that does not play BDMV on BD-R?
