im still having a few problems making copy films on dvd can anyone help................ when i play a copied film which has been done on a friends pc it plays perfect,but if i make a copy of the same film on my pc when i play it back it sticks and jumps every now and again. ive tried all the usual things like reducing burn speed and trying different media (branded g04). thought it could be a problem with my dvd player,but the original copy plays perfect ( same media). could this be a problem with my dvd burner? its fairly new but do they require cleaning? any help appreciated. thanx in advance.
