Comment 14 for bug 349011

I understand the reason for not fixing this. Personally just ignore the adjust disk usage button and guesstimate how many episodes of whatever will fit.
If 2 episodes of a hi-def WW2 blockbuster results in a 3.1GB ISO then 3 episodes (161%) might just about fit 4.7gb but do you know what, life's to short.
IME a 13 part series of standard res 'hour' long shows fits on to 4 DVDs. I only have images of one series to hand: the 3 episode images were 3.3, 3.4 and 3.5 Gb; the 4 episode image was only 3.7Gb.
