i wonder if ethernet cables would make good video cables?
right now i'm using one that's shielded but .. i'm dumb so it doesn't have enough vias for a full SCART connector (that i'm actually putting through DE15 connectors since they mate better and don't get flaky) so the audio ground is going through the shielding ... which is a dumb idea and causes a lot of noise (but it works fine as long as i don't turn the volume up too much)
i'd have enough vias if i tied the R G and B grounds together into one wire but i'm not sure if that's prudent
