Movie sync doesn't work good

[KILDONG]

Hello. Sorry poor english.

When i play game "tantei opera milky holmes 1.5 ULJS00485" with ppsspp version 0.8.1-1173 , Opening movie works perfectly sync.

But when i play same game with ppsspp version 0.8.1-1269 ~ 0.9.1-60 , Opening movie sync not good. (fast-slow repeat)

if use option "vsync", it works better then "no vsync", but its not perfect.

This problem appear many games using movie, not only this game.

My system is i5-3570 , 8G , Radeon 7850, Windows7 64bit.

Somebody help me please... how can i fix this problem?

Goodday
