AVID 1:1 ROLLER FLIKER

HI

I AM USING sd MOVIE AS QT REFRANCE IN AVID 1:1 CODEC.

THE ROLLER IN MY MOVIE IS FLIKER

BUT WHEN I PLAY THE SAME ROLLER FROM AVID MEDIA COMPUSER IT IS GOOD ( NOT FLIKER )

ONLY AFTER ENCORE MAKE THE FULL DVD ( INCLUDE MENUS AND SUBTITLES) THE ROLLER IS FLIKER

I TRY TO CHANGE TO UPPER AND LOWER FILED BUT IT IS THE SAME PROBLEM

WHAT CAN FIX THE PROBLEM ?
