Re: Question for those who are using NL location recorders.



Thanks Jeff-

That would seem to indicate that file corruption would be most likely on the
DVD. That makes perfect sense. One more question. There was some talk
about burning two disks, one two-track for telecine and editorial, and a
second iso-disk for sound. I talked at length with the Tech Super at Encore
this morning and he said that can easily strip off the first two "tracks"
from a poly Bwav file for transfer, and then send the DVD along to sound
with no problems. That would seem to negate the need for two disks. Any
thoughts?

Regards,

D.
