Could someone please help me with this frustrating matter. After i have downloaded a film and burnt it to disc, it plays perfect in the DVD player but on every film the picture seems to jump every so often and sometimes the lips go out of sync for 10 to 15 seconds, which is very frustrating. 
Could anyone suggest anything, i have tried using different discs but it is still the same. Any ideas please please let me know.
Thanks
