Well, the app that Fruittrader mentioned looks useful, the only downside you'd have to use the built in TV video player.
If you want to use a good quality video app, then CX File Explorer would let you pair it with any player of your choice. It's free, and shockingly eas to use.
Step 1. Download CX file explorer (either on the TV if possible, a connected mini pc or a android box, either would work)
Step 2 Find your laptops on the network and create a link to them in the app.
Step 3 Click the link and accesss your videos.
