Rendering for HD what ratio?

Hi there, i hope someone can help me, i gave a wireframe animation that i had rendered out of maya at 1920 x 1080 as a tga sequence with an alpha channel  to a production company using avid, it played absolutely fine when i played it on my mac, but the lines on the wireframe went really crappy quality for them on avid and even previewing a single frame until they figured out i had done it at 10:1 ratio and then they had to convert it, what does that mean and what ratio should i render it out for television programme and where is this option in the render settings?
