ok. u all have probably used DVD-Rs with different branding but little do u know that the name on the packet is not who physically makes the disc. there are different manufacturing plants and each ranges from good to pathetic.
here is a program that will allow u to read the maufacturer of the disc. This can help u identify which brands are better and which to stay away from. u need a dvd writer to use it.
u should stay away from media with this manufacturer:
CMC magnetics
Princo
