-Dear Hilton,
-I would advise that you adopt open (i.e. non-propriety) standards, as these have the best chance of remaining readable in the long-term future.
-Propriety formats are dependent on the continuing existence of the firm who markets them, as well as the continued support by this firm, even if they continue to exist.
-This is in my opinion very risky.
-For documents I am aware of an ISO standard that is targeted at archival, known as PDF/A (see www.pdfa.org).
-For audio and video the situation is less developed, and there are as far as I know no standards specifically for archival.
-In both cases I would recommend that data be saved without lossy compression, and again that open standards be sought.
-Hence mp3 and WMV should be avoided, both because they are based on lossy  compression and are are propriety.
-The audio format FLAC on the other hand is open and does not employ lossy compression.
-I hope this is of help,
-Best regards,
-Thomas Niesler.
