I gave my writer for service but still not writing properly. PLease help only 1 week left on warrant

i gave my samsung TSST Sh w162C writer to a samsung service center because i was getting a write error whenever i was writing dvds with it. i already posted the problem i had some time back with a nero error log at

http://forums.afterdawn.com/thread_view.cfm/406158

i have bought a bulk of the substandard DVDs which i agree are not very good but it is not possible that each and everyone of those dvds are bad. and when i went to take my writer from the service center under the action taken section it said "buffer replaced". would this have solved my prob or they have not done their job properly. BTW please suggest what i should do cuz i only have a week left for my warranty to be over and i dont want to pay for some major fault that my writer could have .

 

looking from your last post,you have not taken the advice that was given
you need to use better media
the last log,burned 100%,but you had the verfiy data tab ticked,which has shown some disk read errors
only when you use better quality disks,will you narrow the problem down

 

Now I can't understand people! They ask for advise and then disregard what was advised and still instist on using inferior products that may have caused the problem to begin with! Why are people so stubborn? "Oh I bought these disks on sale! why aren't they working?" I guess with people that don't listen to advise are doomed to let history repeat itself .... which in this case are COASTERS! Starting off with crappy media is the most significant reason why most errors occure in DVD burning... but keep using the cheap stuff (which in the long run makes their failed burns expensive!)!
