I have not been able to burn a DVD that does not cause playing problems. I have movies from my dvd camara edited in Studio 8 and ulead and burnt to dvd. I also have backup dvd movies made with Xcopy Pro, that when they get towards the end the picture seems to go "Blockie" and my dvd player stops working. I have upgraded my home dvd player to a sony and also upgraded my pc dvd writer to, no avail. I have win xp 512 ram pent4 and 2 80gyg hard drives. I edit on the drive that does not contain any opp system. The problem happens on any dvd player that I have used. Im thinking along the lines of: Is my graphics card causing problems, do I need a Video card as I have not had any other problems, or is it because Im using dvd- disks. I have tried different makes of disk. The dvd writer that I have now plays and records both format. Do I try + disks. Please help as its driving this sad old git round the bend.
