Lords Of Dogtown

Hi Guys I have had trouble with burning lords of dogtown like everyone else however I did manage to copy it decrypt it and Burn it all with one program dvdfab express platinum however the first minute or so is missing when I play it in all my dvd players but when I put it in my computer it is all there and everything is on the disc including the first minute I used dvd shrink and burnt another copy because it showed and played the first minute on my computer but when It was all done burning the first 2 minutes were still missing I was wondering if there was any way with any program I can retrieve the first few minutes from my burnt dvd and burn it with another program for a full copy. Thanks for your help guys
