TV for retro gaming?

Are you seeing scan lines (moving across the screen) or the individual pixels? What cables are you using?

I'm seeing the scan lines, using AV red white yellows with a gamecube. Is this abnormal for this tv?

And around some text I see a swirly kind of effect... I think it's just the scanlines. My mom says it reminds her of neon lights and it has a kind of shimmer. I think it's normal though because I looked at this video:

and on it the scanlines are very prominent as well. So I think I'm just seeing the scanlines or weird interlacing artifacts as described by:
