i think they are homebrew dvd's ? so that means generally that they are 4,7 GB's max in case of single layer
so that would be 13 * 4,7 GB = 61,1 GB's
if he used Double layer, then it will be around 120 GB's
looks like i need to make space on my server

or hook up an external drive....
(and a lot of patience depending on your upload speed, i can receive with +-1100kb/sec)maybe its a better plan to ship a spindle of dvd's
