CI and ECP 4100  

Has anyone had problems using the CI v5.2 on a ECP-4100. I have noticed a bending on the image on the raster. Its most pronounced on non-anamorphic 1.85 images.(I assume because in 2.35 mode the bending is in the black bars and not in the image.) I have tried several resolution on the CI and they produce the same effect. I also have a DVDO that I have used though the same cable, but that does not produce these problems.
I am using the component output of a Sony 7700 in the CI. I also tried the S-Video, but the same results. I have tried putting a macrobuster on the green side of the component output, but same problem. Here are a few pictures I took of the inside of the blue lens as well as a screen shot of how it affects the picture. I am only testing the CI thanks to Hi-Rez, but if I cannot resolve the problem, the increase in picture clarity and controls do not outway the use of the DVDO that works well....

I am currently using 800x600. I have tried 1024x768 with the same results. I have not tried 720, but will do some testing tonight.

Did more testing and found a few interesting things.

1) A computer at 800x600 or 1024x768 at 60Hz to the projector produces a normal image.(Signal passes through the same cable I have connected to the CI)

2) If I swap the cable to the second input on my ECP (I have a dual BNC card), 98% of the distortion is gone. There is just a small edge on the right hand side, but it does not seem to be enough to notice it on the screen.

After speaking with Joel at Hi-Rez he wants me to try a pass through card(a 2 BNC card, but one is an input the other is a passthrough which will be terminated). According to him many of the dual card had problems with some doublers/scalers. I should have the card in a few days and will test it with the CI. From what I have found there definatly some compatibility problem with the CI and ECP. Hopefully I can find the right combination to fix the problem since the CI does produce a much better picture than my DVDO....

I made progress on getting rid of the problem. I am using a terminated input card at 1024x768. Most of the problem was gone, but there was a slight triangle section near the top of the raster image. After changing the setup of Frame Sync from ON to OFF the picture straightened out. Not sure what I did, but I will speak with Joel on this issue in the morning. From looking into the CRT so much I think I have a permanent image of Stuart Little on my cornea. (The 1.85 images were the ones giving me the problems. His disk was just convenient. Go figure...)
