Well, I wish this issue was as simple as a software problem. All of my SD DTiVos (7) are Zippered and locked at version 6.2-01-2-321. One of my DSR7000s has recently developed this issue. I first thought the HDD had gone south, most pixelation issues I've dealt with involved HDD issues. True to course, if I yank the S-Vid all is well, plug it back in and it reappears almost immediately. I'm hoping that I won't see further degradation as I need to use both composite outputs in my current config. If I do see further problems I'll swap out a power supply with one of the other fully functional DTiVos and report the results back here.
