Actually, you can see the DVD Laser, but the CD Laser is not visible because the CD is Infrared while the DVD Laser is Red

I was thinking:

It's impossible to see laser, cause it's InfraRed (even you wrote in this video)...

But then I remembered that camera lenses captures lasers, so they are visible through the camera ;DDDDDDDDD
