Oops! Sorry for delay in replying Rob. When downloading through a 'busy' USB line I used to get dots and trails during image download so since then I always pause the guiding to free the line when I download images. I use the same USB line to go to a hub where I have the QHY8, the mount and the guider (QHY5) using the same line.

The S-Video cable should have some kind of mesh in the rubber coating ideally that you can solder on both ends to the plug. Like a coaxial TV cable. The thin ones don't come with this extra cable shielding. In my case it did reduce greatly noise interference/banding in my pictures although I use ferrite blocks in all my USB lines too now. Better more than not enough
