VGS,

Thanks, and your explanation of how the VIP handles interlaced video explains a lot. I've been selecting triple buffers, and have issues if I send more than one video source into the frame buffer. I'll try to process with double buffers and see if it makes a difference.

My last test on Friday involved going back to progressive video by using 2 deinterlacers, and that works, but of course the output is all over the place vertically on my monitor, which is expecting interlaced NTSC, not progressive.

I'll be talking to the FAE this morning about access to that core. Thanks again.

Jim
