said by Greg2600:MundoFox is not getting their programming from America TeVe. They are getting it from RCN Columbia and Fox international along with some of Fox Deportes productions. America TeVe is just an affiliate. The channel 479 is the displaced America TeVe network that was 34.1 in your area so now it is 34.2 . Also America TeVe has plans to launch MundoFox in HD next year in NYC according to a press release I saw.
Essentially MundoFox made an agreement, at least in the NYC market (Chicago and Miami too), to broadcast over WPXO, a NJ-based Low Power station (channel 34 ATSC). Now, that said, I read that much of the programming will be provided by the America Teve network out of Miami. So with that said, I'm kind of wondering what is going on channel 479?
I kind of wonder what MundoFox is bothering with the low power station though, since nobody can get that without a moderately powerful house antenna. At least in the NY/NJ market, I cannot imagine this one getting an HD slot, since there's no chance of them broadcasting in HD OTA. Though the Chicago affiliate WOCK has it in 720.
