The DVD media has to be a match for the DVD drive (dvd R- R+ or other ?)
xfburn seems to be ok for me, also since you are on the main edition (Gnome base), Gnome baker might work, but I have found xfburn to be more reliable with media http://www.techdrivein.com/2011/03/9-go ... s-for.html
--you can try others, but I would be careful about media (DVD) being used, as well noting that some brands of media may be better than others, for example the cheapest(not a major brand) may not always be the best..
--I tend to try Maxell, Fugi, being that they had good tape technologies (a good background in magnetic media/coatings, and had little problem switching to optical versions..)http://www.techimo.com/forum/general-te ... brand.htmlhttp://www.best-dvd-burning-software-re ... -media.asp
You can check, or choose on your own, your experience will tell you which works best: and since you can buy a single copy of a media (disk) you can determine that
It is also worth considering a rw dvd media in order to use as a scratch disk: many people probably create too many write-once (Read only) dvd media and hardly use them again
--a matter of organization/planning: it does help to be organized, although it can be a fair amount of work
