My first priority and focus here is to get basic playback of video
formats burned to Blu-ray UDF "data discs" for archive using a Blu-ray
player (UBD-K8500). This includes basic playback functionality (i.e
skip) or browse file structure with the remote.
My thought is that if "compliant .m2ts" playback works from "data disc",
there is a reasonable chance next they also can work using a Blu-ray
video BDMV structure. I just expect this also offer more advanced
features, though this is not critical for archive of "intermediate
source" format .
And yes, I have tested that both DV video transcoded with x264 and HDV
mpeg2 video copied pass-through each playback ok as m2ts when the
respective pcm and mp2 audio formats are transcoded to AC3 (FFplay, VLC,
BR-player).
