i really dun follow what u mean by "if any android box can output the hdmi and av output at the same time as same function as astro box"

i thought u meant if u can have hdmi output and a second av output from the same android box, i.e. can output to 2 tv's. that's i think possible but better check with seller(s).

but if u mean u want astro channels from an android box, i can't comment. i only know astro is astro, all other boxes are illegit.

what is this A/V in "a/v to other room tv"?

how is it related to the astro box and main tv?

What box are u using boss ?
