List of discs by developers

Some bugs such as are trivial to fix, if we can confirm the situation with an original CD/DVD.

Brainstorming for the checksum
A checksum can indicate, if the developer uses the same media as the user who reports a bug. A user can also verify the media. Broken media, or different release can result in strange bugs which are hard to track.

Requirements on the checksum:
 * all users and developers should be able to generate and verify the checksum
 * the checksum does not need to be secure. Just want to check if we have the right CD at hand.
 * md5 is probably strong enough and short
 * checksum must be independent of the user environment (i.e. localization)
 * checksum method must work on media with copyright protection
