The current logo detection does this in CommDetect::SearchForLogo(). Look
for the following lines near the bottom of the method:
nvp->JumpToFrame(0);
nvp->ClearAfterSeek();
I'll take a look at your patch tomorrow. I've been working on logo
detection a little, but if you have a better detection working then
I could look at patching that in instead of tweaking what I currently
have in CVS.
