It is possible to connect a Chromecast to a cable box Comcast and be able to play youtube video on your TV.
You unhook the connection from the cable box to the TV and connect it to the VCR input. You purchase a short cable and install it from the VCR output to where the cable was connected to the TV. The TV will get the cable box signal through the VCR with no problem when you are not using the VCR. If the cable box was connected to the surround sound or Home Theater and then the TV then connect the cable box to the VCR and then the surround sound or home theater.
Yes you can. Just connect it to the cable box, and set it up correctly.
You don't. You either connect the PS3 to your HDTV with HDMI and the Comcast box to your HDTV with HDMI cables like I used to have or you connect the PS3 and Comcast Box with HDMI cables like I did to my home theater and then connect the home theater to the HDTV with a HDMI cable. My Comcast box is HD and I have a Sony HDTV and Sony Home Theater equipped with a HDMI repeater. If you are talking about connection for the internet it is not done with a HDMI cable, but an ethernet cable
Your freeview box should connect to the TV Ariel on the top of your house. The Sky + cables connect to the Sky dish on the side of your house and will not work with your freeview box. If you have Sky there is nothing on freeview that you can not already get on Sky (even if you do not have a sky card).
Not knowing where this wall cable goes TO or comes FROM prevents any more help. Would suggest you run a new cable to these two items.
