1. Connect Cable box 1, BD player, Apple TV, DVD/VHS, and Game to the TV. Use HDMI where you can. This is for viewing/playback.
2. Connect the AV output of cable box 2 to the AV input on the VHS. Select this input as your source. This is to record from cable box 2. Set the box to the channel you want to record and the timer on the VHS. You can't change cable channels with the VHS.
3. Connect the ova antenna to the antenna input on the TV. Set the TV for over the air and run channel scan This is for watching ova TV.
The tuner in your DVD/VHS is probably not an ATSC digital tuner but if it were you could split the antenna lead and connect to both the TV and recorder.
