I posted awhile back on not being able torewrite or erase my dvd+rws.Ithought it was my disk brand so I went out & bought new ones(fugi).I was able to rewrite over maybe once but that was it.I used programs like copy to dvd,Tmpgenc dvd author,nero,120% & many others & cant erase or rewrite over.It keeps telling me not a erasable disc but it is.I even tried dvd info & it says it is a +rw.My burneris a Khypermedia (&yes Ive updater firmware)& using Fugi dvd+rws.Any help would be greatly appreciated because Im going broke $$ buy dvds.
