I paid for ANYDVD, and I keep it up to date. Lately, I have had my CSS key archive wiped out each time I uninstall the old version and install the new version. Is my problem caused by the uninstall process?
Updates are coming very frequently lately and I have trouble installing the
new version when I do not uninstall the old one.
How does one have the most current version running each time to avoid the notification of the same new version?
I like the idea of having the CSS KEY ARCHIVE filling up. Any ideas out there?

Uninstalling doesn't give you the option to save your CSS archive. You can, however, manually export the archived keys to a file and then import it when you re-install.

Go to the CSS keys section under the Video DVD portion of the program. Highlight CSS keys at the top that has the + or - next to it and export it. This contains all your keys if you highlight CSS Keys and not a single key. What it's actually doing is exporting the registry info that AnyDVD saves concerning the keys.

It's up to you, of course, if you want to use this feature. Keep in mind if Anydvd happens to get the CSS key wrong the first time, it will then aways get that key wrong in subsequent attempts, because Anydvd will be retrieving the wrong key from the archive instead of trying to obtain it properly again.

Maybe AnyDVD should save the CSS key archive like it does with the other settings.

Me either, I never understood how the CSS key archive could benefit me.

"There are many reasons to archive the CSS keys.

Depending on the situation (region mismatch, brute force attack required, amount of vulnerable blocks) calculating the CSS key can take quite long.
Keeping this key in an archive will speed up the process in the future.

Some drives (RICOH, Philips) can reveal the correct title keys due to a firmware bug even on region mismatch, but it is required to open and close the drive tray after key exchange.
I believe AnyDVD is the only Software, that does use the "open/close tray trick" to get correct title keys from these drives, even if there are not enough vulnerable blocks available for a brute force attack.
Opening / closing the tray is very annoying, but because of the CSS Key archive this has to be done only once. The next time you insert the same DVD, the keys will be taken from the archive.
Sometimes AnyDVD is not able to get the key with a brute force attack, and it will "guess" the correct key (usually correctly). You can change/verify the guessed keys in the archive. If you change the "Substitute" flag from yes to no, AnyDVD will take the "guessed" key for granted and will no longer display a warning message.
If you messed up the archive, AnyDVD can delete single keys, all keys for a title or the whole archive if you wish.
You can even import/export/edit keys. e.g., you have a second computer with a drive, which can reveal the keys without brute force attack. You can transfer the keys from one computer to another.
Last but not least, you can compare / exchange keys with other software, e.g. DVDDecrypter.
The key archive is kept in the registry, together with a MD5 checksum to identify the title the keys belong to."

... exactly my thinking ....

I haven't kept the key archive - for a great while - either
- and never any trouble with AnyDVD cracking CSS - since Disabling

Why would you even want to keep them ? ( edit: Oh ! )
I never noticed any difference in the 'speed' of 'Decryption'

Seems like a waste to me, I've never needed to do this, it always cracks the CSS key.

Same here.
