I'm new at this and have just made it to the point of configuring the DivX Codec. I went to VIDEO menu, choose COMPRESSION, and CONFIGURE on my DivX codec. under the DIVX CODEC tab, vertically center and on the right side, there is a group of options in the "MPEG4 TOOLS" box, but they are all grey and unusable, what can I do about this? I guess I should mention I'm running on XP, using VirtualDub 1.5.3 And I'm also wondering if it could simply be that I'm not using DivX Pro, just DivX 5.0.2 thanks!
