Image flipping in iChat using USB cam

I bought an iContact camera by ezonics because the box advertised that it works with OS X and iChat. The thing wasn't recognized by iChat until I downloaded the ecamm software. In any case, when I open a video window in iChat the image is extremely poor quality (very dark and grainy, no matter the lighting conditions) and it flips upside down and back to right-side up continually. When I open a video window with the ezonics "webcam monitor" program that I got from their site, it's good quality and doesn't do the gymnastics routine. I tried the IOXperts thing as well, still no results. This is on my iBook, I just want a webcam for travel so I can iChat AV with my family, don't want to drop another $150 for an iSight (that's what I have at home on my G4 tower.) Any advice and/or suggestion would be greatly appreciated!
