Wikipedia wrote:Albinism (from Latin albus, "white"; see extended etymology, also called achromia, achromasia, or achromatosis) is a congenital disorder characterized by the complete or partial absence of pigment in the skin, hair and eyes due to absence or defect of tyrosinase, a copper-containing enzyme involved in the production of melanin. Albinism results from inheritance of recessive gene alleles and is known to affect all vertebrates, including humans. While an organism with complete absence of melanin is called an albino (US /ælˈbaɪnoʊ/, or UK /ælˈbiːnoʊ/) an organism with only a diminished amount of melanin is described as albinoid.
Albinism is associated with a number of vision defects, such as photophobia, nystagmus and astigmatism. Lack of skin pigmentation makes for more susceptibility to sunburn and skin cancers. In rare cases such as Chédiak–Higashi syndrome, albinism may be associated with deficiencies in the transportation of melanin granules. This also affects essential granules present in immune cells leading to increased susceptibility to infection.
In humans, there are two principal types of albinism, oculocutaneous, affecting the eyes, skin and hair, and ocular affecting the eyes only.
Most people with oculocutaenous albinism appear white or very pale as the melanin pigments responsible for brown, black, and some yellow colorations are not present. Ocular albinism results in pale blue eyes, and may require genetic testing to diagnose.
Because individuals with albinism have skin that entirely lacks the dark pigment melanin, which helps protect the skin from the sun's ultraviolet radiation, their skin can burn more easily from overexposure.
The human eye normally produces enough pigment to color the iris blue, green or brown and lend opacity to the eye. However, there are cases in which the eyes of an albinistic person appear red, pink or purple, depending on the amount of pigment present, due to the red of retina being visible through the iris. Lack of pigment in the eyes also results in problems with vision, both related and unrelated to photosensitivity.

I don't think anyone at dtv claimed these were aliens,just the guy in the video..
The very fact we have this recessive gene leads us to wonder where it came from..
& wonder about the copper & pineal & melatonin..maybe there's an important clue there for those trying to fix the human genome..not that we'll benefit from it..well you never know..
I like the Julio Fernandez alien encounter case I reckon they look like that..(see 5th post up from bottom of page in link)
