I see what you mean - and think I agree with you :)

By the same token someone who switches to a mirror with dvd's that didnt 
have them will get an extra 25 GB they didnt expect.

The latter is preferable as there are also *dvd.iso to consider.

The issue now is that we will need to get existing dvd mirrors to comply 
....

Guys - any chance ....

Or do people not agree ....
