"Starting in 11.10 nautilus reports file (iso) size in actual GB, but brasero incorrectly uses 4.3 GB as the capacity of a dvd -r

The actual numbers of a dvd -r are available space - 4,706,074,624 bytes/2,297,888 sectors/4.7GB/4.38GIB So an iso that is near the true max file size of a dvd -r, while it will fit , is now rejected by brasero as being to large for the media

Ex. - have an iso that can and has been burned to dvd -r

Actual size - 4,691,394,560 bytes Nautilus/properties reports - 4.7 GB (4,691,394,560 bytes) Brasero shows iso size as 4.7 GB, media capacity as 4.3 GB, refuses to burn

(as a comparison a dvd burner, ImgBurn, that just uses bytes/sectors for filesize & media avaialble space shows this & will burn iso size - 4,691,394,560 bytes/2.290.520 sectors : dvd -r media - Free Sectors: 2,297,888 ; Free Space: 4,706,074,624 bytes

K3b use GIB so it also has no problems burning the above mentioned iso

So it would seem brasero, gnome/nautilus, need to get on the same page here & brasero needs to use the same method for both filesize & media capacity, either GB or GIB"
