Hey, I have this problem again. The DivX files are slow during playback with any player I use. Here's the info:
VirtualDub Version: The MPEG-2 supported version (1.5.1)
Video Codec: DivX Pro 5.0.5, 1000 Bitrate
Audio Codec: MP3 96 Bitrate
Encoding method: 2-Pass
Filters: Sharpen by 8
MPEG-4 Tools: Quarter Pel, GMC & Bidirectional Encoding (When all three of those are checked, what does it mean when it says "Unacceptable Rate Control Mode"?
Video Card: 3DFX Voodoo 4 32 MB
Desktop Properties: 16-Bit.
I have tested Direct3D and DirectDraw via "dxdiag".
I don't have NetMeeting enabled like they mentioned about on DivX.Com.

Can Anyone Please Respond With A Solution?
PS: I have solved this problem before, I just forget how I did it.
