That is true. But only really if you had to back the lot up in one go. I tend to back things up as I download each collection, so it doesn't take that long each time.

Obviously if you had to burn 120 DVD-R's, going on an average of 4 minutes per disc it would take 10 hours! But more realistically it would take longer per disc due to needing to sort the files for each disc and queuing up the discs.
