Comment 16 for bug 349011

I had almost the same problem with my devede on any distributives. After using Adjust disc usage the size bar showed 99%. After finishing encoding DVD i had a size ~3.6-3.8 Gb. Then i started to edit manually video bitrate to have 112-113%. But then i edited file:
sudo gedit /usr/lib/devede/devede_other.py

there you should edit this block to get the size you want:
if 0==active:
tamano=170.0
elif 1==active:
tamano=700.0
elif 2==active:
tamano=750.0
elif 3==active:
tamano=1100.0
elif 4==active:
tamano=4200.0 <<===== (i have 4600)
else:
tamano=8000.0
after that compile this file:
sudo python -m compileall /usr/lib/devede/devede_other.py

And after using Adjust disc usage button you will have full size dvd 4.2-4.4 gb. Have fun!
