Mag 254 - Cannot use HDMI and RCA at same time
Mag 256 - Can use HDMI and RCA at same time

How does Mag 322 do? anyone test, just insert the RCA into it while HDMI is running, does it get blacked out?

Also, anything exclusively different about this device from 254 and 256? same function? screen etc?
Ive been reading about Informir blocking some IPTV URL's and there are custom images etc so is that an issue with this one too
