Large species of octopi (edit: errr... octopods or octopuses, octopus being from Latin rather than Greek) have, in problem solving tests, been shown to be as intelligent as feral cats, which are generally more intelligent than (or at least not as intellectually lazy as) domestic cats.
If you are looking for an intelligent alien life form, look no further. Octopi (edit: errr... octopods or octopuses) are molluscs, not vertebrates.
And then look at the Squid; he's pretty darn bright for a mollusc, too.
Anyway, to the point, Octopi (edit: errr... octopods or octopuses) like HD TV.
