look around the web for a live stream from the channels you want then run a cable from your pc to your tv.
you wont be able to directly tune in say with a sat tv box as the satellite that broadcasts it will likely not reach you so the web is your only real option.
word of warning though. there are many pctv apps out there that claim thousands of channels watchable. the vast majority are malware and some charge for pro versions to unlock the main features. better to try browser sites rather than trying to find an app like freepctv.
http/www.mtv.ca/ has live streams but you will need a vpn or some other solution to bypass the regional restrictions.
