if you get tsmuxer working you can try --avchd option for it, possibly with
re-encoded (into much smaller bitrate h264) stream..

yes, it will be lossy, but at least we will learn if any combination of
open-source tools we have can produce (playable in at least your hw player)
those 'bd structure on dvd' disks..

If it works as-is (it does re-encode).. you probably can tweak it a bit
without much understanding )

yeah, thanks.. While _in theory_  one-time udf image creation should be
much less complex compared to full rewritable udf 2.50/2.60 image.. code
still not written and I struggle with very basic concepts, like what should
be put inside specification-mandated Metadata files..


 Can you load m2t file into tsMuxerGui? from there you can just play with
options until it spit out file or directory tree...
