I just installed a Vizio Co-star and was surprised to notice that there are android apps that cannot be installed on this platform. For example, my Wife's Nexus 7 can install an app for WatchESPN and also for Speedtest.net, yet these are not compatible with the Co-Star. I also thought that pre-purchase I had read that the unit had HDMI pass-through, but now that I have it installed I find that the unit has to be on if another in the household wants to use the xfinity remote to control TV and Cable box. Is my take on this correct? Since the Co-Star seems to run hot, I hate to leave it on at all times.
