This is not technically a microscopy question, but I'm desperate:

I use a mac. I have hundreds, if not thousands, of videos exported into .mpg
and .mov formats over many years of imaging.

Of late, I have noticed that _many_ of my older .mov files are seriously
corrupted on the Mac. It's not the data. Archived movies are the same. It's
the player- Quicktime. It no longer can play the old movies. However, 2-3
years ago, before this problem was widespread, we exported several .mov
files to .avi. These .avi movies (fortunately) play just fine. However,
attempt to export the corrupted .mov files now yield .avi files that look
just like the .mov files- that is to say, they look like garbage.

I have attempted to revert to older versions of quicktime- all the way to
v7.3. No luck. They're still corrupted.

The corruption is not a computer issue. The same movies are corrupted on
many others Macs with current system installations.

As you might expect, this makes for less than stellar presentations, when
half of your movies crash.

Oddly, some movies exported on the same day, using the same software, will
play, and others will not.

Has anyone else encountered this problem on the Mac? Any thoughts?
