SOLVED: ,ogv video plays sluggih

[Slasher]

Hi

I have a video file which plays but it is quite sluggish (slow, stutter) with  a kind of echo.

its is 6.86mbs.

game is 1024 x 768. 32 bit. 3d9

it's .ogv in the compiled Game folder..

Code: ags

 PlayVideo("pierre_death.ogv",0, 0)

Any suggestions for better video play?

EDIT: .mp4 plays Ok at 5.17mbs

EDIT EDIT: Since the widescreen format doesn't add much, I changed the video resolution from 1280x720 to 640x480.
The .ogv now works perfect.
