I'm having a problem using the Canopus ADVC100 to convert a PAL tape to DV. IC Imaging displays the image, but the aspect ratio appears to be distorted by about 10%, i.e. vertical lines are about 10% longer than horizontal lines that should be the same length.

There is also a black band both to the left and the right of the image.

I suspect that the problem may be related to the fact that there are no items in the list of VideoNorms; in fact, VideoNormAvailable is false. However, the list of VideoFormats is correct -- you get 720x576 when the ADVC100 is set for PAL, and 720x480 when it is set for NTSC.

Any idea what the problem is, and how to fix it?

Thanks,

MikeG

Hello,

This problem cannot be solved. The converter should provide a 768x576 video format, but it doesnt. There is no solution to the problem. You could blit the images yourself into a window by correctiong the wrong aspect ratio. This is not simple.
