AsVideo/VideoTexture frame delays

I noticed some frame delays in using the Contour FF plugin. Investigating further, I found that if I have the following chain of nodes:

dx9texture -> asvideo -> videotexture

the texture output of videotexture is delayed two frames from the output of dx9texture.

I’m assuming that there is a 1 frame delay in AsVideo, and 1 in VideoTexture, is that correct? I couldn’t think of any easy way to test it. Must there be?

I can post a test file that shows this if needed.

Thanks!
