How do I completely uninstall divx 3.11

[UncasMS]

there's absolutely no need to do so imho.

it depends on the pack/installer you have.
worst case scenario would be to check your inf file.

these files might need to be exchanged/deleted:
++++++++++++++++++++++++++++++++++++
div3 = 1:divxc32.dll, "vidc.div3", "DivX Low" , , ,
div4 = 1:divxc32f.dll, "vidc.div4", "DivX 3917 Fast" , , ,
divxa32 = 1:divxa32.acm, "msacm.divxa32" , "DivX Audio Codec" , , ,
MPG4 = 1:mpg4c32.dll, "VIDC.MPG4", "MS Mpeg-4 V1 3688 Low" , , ,
MP42 = 1:mpg4c32.dll, "VIDC.MP42", "MS Mpeg-4 V2 3688 Low" , , ,
MP43 = 1:mpg4c32.dll, "VIDC.MP43", "MS Mpeg-4 V3 3688 Low" , , ,
l3acm = 1:l3codeca.acm, "msacm.l3acm", "Radium MPEG Layer-3 Codec 1.2.0.63" , , ,

Open the Control Panel (Start>>Settings>>Control Panel), and select "Add/Delete Programs". Scroll down to "DivX Codec 3.11 Alpha Release" and doubleclick on it.
