I am currently using the Wireless AV transmitter to change channel only (for the 2nd tv)... this is because the quality is really not that good to transmit video.... so i use a very long RCA cable to transmit video and sound instead....
behind the astro beyond decoder, there are RCA and component, so the main TV I use component, then the 2nd tv use RCA....... 1 main problem is the splitter that I use cannot fit in to split the audio (red and white)... so what happen is 1 tv use red and 1 tv use white ... too bad astro won't open the HDMI port if u dont subscribe HD channel.....
Astro byond spilts into 2 or 3 TVs
