Image overlap?

First let me state that I am brand new to Panoweaver.  I have had trouble stiching images.  There is significant overlap of items in scene that I just can't seem to eliminate.  I try messing with the Fisheye parameter but I can't even understand how that works.  Sometimes as adjust the fisheye parameter, the enclosed area doesn't change - sometimes it changes significantly (more than I would want).  In any event the end result is a very poor stiched image.  Now I would first tend to blame the photos but the images stich perfectly with iPix software?  Any advise would be appreciated.

Generally the stitching will be good enough as long as the white
circle surrounds the fisheye image properly.
The white circle in the fisheye image area is used to locate the
border of fisheye image. Its position is determined by both the
fisheye parameter value and the levels (Brightness, contrast,
saturation etc.) of the current image. So sometimes you find it uneasy
to make the white circle surround the fisheye image properly with your
mouse, if so, you may use the arrow keys (left, right arrow keys) in
the keyboard to adjust the slider. Moreover, if the two fisheye images
are different to each other in brightness and contrast apparently,
please adjust image levels by rightclicking on the image with your
mouse.
Please send us a fisheye image pair and let us have a try if possible.

In the trial version, the maximum output image dimension is fixed at
500*250 and so the resolution is pretty low. To have a full-featured
test, please use samples included in trial version.

I have to say that I was having a terrible time stitching panos until I began cutting off the chromatic abberation that forms a ring around the outermost edge of the image circle. Things became much more managable after implementing this in my routine. Now, I have a photoshop action which crops the entire image to a square, snips the outermost ring of the image circle, and then saves to a folder as a tiff image. If the new image has problems, I will go back and use a custom-sized circle to snip the chromatic abberation on an image pair. This usually solves the problem.

I forgot that there is a tutorial for this at Panoguide.com. I'm sorry but, I don't have a link.

Thanks for the advice!  I will give that a try.  I have actually gotten some better results of late just trying differenct camera settings with my Nikon 5000.  I actually received a pdf from Homestore.com with some tricks.  If anyone would like a copy just let me know.

Thanks Jos. That's the one that I was thinking of. I hadn't considered all of the effects of the chromatic abberation around the image circle. Once I saw the problem defined, it made perfect sense. I'm enjoying my stitches much more now that I'm doing this with all of my photos. Really, Photoshop actions make the task time negligable.

I had the same problem when I first starting using Panoweaver. I tried cropping out the blue borders around the image, but Panoweaver has a hard time adjusting to a cropped image--meaning the fisheye parameter gets all screwed up.

To help eliminate the overlap, get yourself a panoramic tripod head. I use Kaidan's and it works wonders. Also, get Kaidan's Quick Tilt leveler. It helps a lot. Use the 50% detent disc and it's all good. Even so, there might be some overlap ... I guess nothing is perfect.

Now if Panoweaver had a more responsive Fisheye Parameter tool, the process would be a lot easier.
