The enlish verb "to check" is an anglicism very abused and used in spanish language. To check is used instead of to use "Revisar" (review)
So, in this part .."Checa el video" it means "see the video, check the video, review the video, etc.
Here, the word "checa" is used in imperative mode. (giving a commandment or recomendation)
So,
Yo checo I review
Tù checas You review
ÈL checa He reviews
Nosotros checamos We review
Ustedes checan You review
Ellos checan They review
The mexican spanish is very different from spanish spanish (from Spain, I mean)
And too is very defferent (not only in accent) to the colombian, argentinian or uruguay and others american spanish.
By the way, the correct name of this language is Castellano (castillian) not properly spanish, because its origin was in the region of Castilla in Spain.
So, be patient in some topics, because altough Pulp, ta0 and me we are spanish native speakers, sometimes, even, between ourselves we can misunderstand into our own language.
