Thanks Jonathan I'll give it a try.. VTHi @Vinylted - what streaming service is it? If it's something like Netflix, it might be a little tough to record.
One option you might want to explore is getting something like a Chromecast - see for example https://www.jbhifi.com.au/collections/tvs/chromecast
You basically plug it into your TV, connect it to your wifi, and you can then 'cast' things from your laptop to your TV.
