Dhsow filter can't connect

Hi to all XVid Developers,

i want to use your xvid encoder in my dshow application. The Filter Graph of my Application is compatible to many different encoding filters but for some reason i don't know the autoconnect function is not able to connect the output pin of my camera filter with your xvid filter.

Does anybody know why? Or could anybody explain mehr which filterchain i (at least) need to encode my camera video?

Regards
