Got it working but Playback is slow?????

I got the video working but now playback is slow can anyone help me. It might be a setting with ffdshow but i can't even open it so any help would be great.

Make sure you have the Ogg Vorbis DirectShow filter installed. Get them here.

The slow playback maybe due to the encoded audio.
Is it mp3 or AC3?

I think it is ac3, but when i put it through G-Spot it says vorbis, i'm new to this so that's all i know
