Don't resize vertically before deinterlacing. As a quick test add only the Bob Doubler filter. Watch the output pane in VirtualDub as you step through the video with the right/left arrows on the keyboard.

And just in case: do you know VirtualDub has two display panes? One for the video before filtering, one for after filtering. Make sure you have the output pane enabled and are viewing it.
