You're a brave man doing video, too <smile>.
Ten years ago I heard of the same problem/practice with 3/4-inch U-Matic.
Twenty years ago (plus or minus) I had this issue with one box of 10 DAT
tapes I bought new back then.
I have probably run fewer than twenty tapes in my DA-38.
With that said, binder hydrolysis is probably an issue with some runs of
coated tape (though I would not expect it with metal evaporated tapes).
So far, I have baked one DAT tape and that made it recoverable. Oddly,
it was an Ampex tape.
Storage conditions make a huge difference. The Library of Congress is
apparently NOT experiencing the need for increased baking times that
other restorers and I have noted due to the fact that they are
transferring their holdings which are stored in proper storage
conditions (which I do not have the specifics for at the moment). Is it
possible that your location in Israel is a dry one (I do recall a fair
amount of desert there, though I also recall that much of the population
is in the coastal region) which is reducing the amount of binder hydrolysis?
Trying to generate a "big picture" from all these data points is
interesting and sometimes frustrating, and I do not think we'll ever
know the complete picture due to the lot-to-lot chemistry changes and
manufacturing tolerances that have been documented.
