How soon before we start to see complaints that editors can't get
reliable playback when AMA linking to an AVCHD clip stored on an LTO5
tape via LTFS?

versions. But, you can use LTFS formatted or the TAR-compressed file
backups of the earlier tapes - and both are open source formats.But if
you use LTFS, the archiving software can retrieve just the files you
wish but (given the slower seek times of tape) if they are close
together on the tape, it will probably be faster if you retrieve groups
of files.

archived to a raw HD. What is the time difference in retrieving data
back if I need to fix a 3 shot section in an hour show? Will those LTFS
LTO-5 drives appear like a media drive so I could in theory consolidate
the necessary media back to my normal storage to do the fix?
