I want to replace my current 508 with the 522/625. I currently run the rf out of the 508 into a channel 4 combiner along with the ota feed. The resulting feed then goes to a splitter that distbributes both the satellite & ota programming to 3 tv's. I want to use the tv2 rf from the 522/625 receiver (since it is stereo) and distribute that signal just like I do the 508. My tv's are still the analog type & I don't have any excess composite inputs available. Will this work? Will I have to have the receiver is single/shared mode to achieve this? Will I still be able to record a separate program on tv1 & then view it later?
