This is a difficult one. DVD’s are subject to scratches and even the smallest scratch near the info or boot sectors of the DVD can render it useless. We offer a 1 year return to base warranty on the work we have done. If your DVD stops working within a year of the transfer due to malfunction of the DVD, we will re run the conversion (provided you have the original tapes). We will not honour this warranty if there is damage to the DVD in any way. This includes the top surface of the DVD. Any scratch on the printed surface can damage the coating and cause a disc to malfunction. When you write on the disc, use a felt tip pen, preferably one that is intended for this purpose. These can be obtained from your local stationary store. Some solvent based markers can also damage the surface, so be careful. If you want anything printed on the disc, please let us know, it’s one of those included items we referred to. It is very important that the DVD is cared for and stored correctly.
