Andrew,
Using the last email fix suggestion (and ignoring the previous to that
email suggestion), bdwrite no longer crashes but there is an error message:

+ mount -t udf -o loop /tmp/bd_20220502-191150/bd.udfs
/tmp/bd_20220502-191150/udfs
+ bdwrite /tmp/bd_20220502-191150/udfs /tmp/bd_20220502-191150/bd.m2ts
*bad stream idx 2 in pgm 0*
+ umount /tmp/bd_20220502-191150/udfs
+ echo To burn bluray, load writable media and run:

But unfortunately the bluray media has *no audio* playing which is the
whole reason for choosing Truehd.  The Info Menu on the LG player reports
audio type as "DD trueHD".

BTW: my linux bluray writer and the RW bluray media are often quite sketchy
-- sometimes  the plug n play writer disappears and I have to reboot to get
it back and I suspect the media is just getting worn after writing the same
area over and over again.  Anyway that is why it takes awhile for me to
respond.
