NetMD stuff is quite well documented in the 1934 AVC documentation. The
USB devices use AVC over USB instead of AVC over FireWire. Alas, that
documentation is non-free. The copy of the MD Audio document I happen to
have specifies the recording time as an optional info block. The info
block ID and stuff like that are in the general AVC Disc document and
the way of querying info block items in the AVC Descriptor model
document. I can look up the specific command tonight when I have some
time for it.

We don't know about device support, though. Neither for implementation
of the specific AVC info block field in the NetMD interfaces, nor about
which MD records write a timestamp to disc.
