It sounds normal. TV video works though interlacing frames, where a computer monitor doesn't. It'll look fine if you export it to your TV. Though if you just want it on your computer, there are various ways to deinterlace it. I know adobe primere has an option...
As for how it looks on other computers, I have seen some computers that seem to show the interlace lines worse than others. If you could just deinterlace it, everything would probably be fine... Try exporting it to the TV if it's still in DV format. I bet it'll look fine there...
