I am currently using windows 7 and windows media center with the ceton infinitv 4 and two ceton echo extenders. I would like to switch to JRiver. Will my ceton devices still work as they do now? Would I get all of the channels That my package provides? Would windows media center run in the background? If not is there any way to use JRiver for everything but live tv/dvr and continue using wmc just for that.
