3 GB can be a substantial file transfer and there are many factors that can contribute to taking a long time. They include:

A/V software checking each file.
Extracting compressed (e.g., ZIP or RAR) files during the copy
The number of individual files being copied
The copy program used (some are very slow)
The hardware configuration
Other processes going on at the same time
Whether copy verification is used

Was your DVD kept in a brown translucent zip-lock bag? Was your DVD being stored next to industrial strength cleaning chemicals? We must also factor in the average humidity of Brazil's east coast to be certain.

Although mentioned jokingly, this part was accurate science, for a longevity conversation. :wink2:
Just not a speed conversation.
