Louis A. Mamakos: |The even/odd fields thing is not (as) noticable when the capture window is |increased up to maximum size. I'll stare at it some more, but I think that |I'm willing to believe I've been seeing artifacts. Did you try this suggestion I mailed you last night? It sounds like this is what your seeing. The patch I suggest will cause fxtv to do only odd frames when capturing less than 240 scan lines -- currently it always does both, which can generate interesting aliasing artifacts for smaller capture resolutions. Randall Randall Hopper: |don't see it. This is because it's blasting both the odd and even frames |right on top of each other 30 times a second. If we're talking about the |same effect, you can make it go away by editing tvcapture.c, search down |for ODD, and uncomment that if statement. | |Maybe that should be the default (?)
