Could that be an EMC problem between the WiFi RF and the TV-HAT itself? I have always been wary of using the on board WLAN with the TV hat for that reason though I have just tried it with an original Pi-Zero W and it seems quite happy streaming full multiplexes and individual channels without any errors. The TV hat has a ground plane as the bottom layer which presents some sort of shielding when mounted above the PI. If mounted below, the unshielded TV RF circuitry is very close to the radiating WLAN antenna without any shielding between them which could lead to all sorts of overloading/intermodulation effects. That might explain your experience.
