The opposite isn't really possible. Rick has no control over your YouTube subscriptions (just like if you want to cancel on YouTube, YOU have to do it, he can't control the subscriptions. It's only possible the other way because he's the boss here ;).

If your TV has YouTube, it probably has access to a web browser as well, most smart TVs I've seen do. You could login to the website through that on your TV and watch them that way. Or you could broadcast to your smart TV is it supports it from your PC/phone, or if you have a laptop you could get an HDMI cable to screen share with the TV. There's probably some way to get it into your TV as is now. But I can't suggest what without knowing your setup.

My problem with this is a little more convoluted. The web site subscription was set up by a guy in accounting here at work for me. I try not to spend too much time on the videos here at work and watch the free ones at home and watch the extended cuts here at work. At home I thought I could access the Extended videos through my personal account vs setting up a second YT account (if that's possible) using my logon for the web site then bouncing back and forth between the two. My TV has a box that broadcasts the sound to my hearing aids so I like listening to the videos on the TV rather than the computer. Thank you for your response.

Yea there's no way to do that I don't think. I don't think he can even "give" you a YouTube subscription if he wanted to. It's all controlled by YouTube themselves over there. I believe your only solution is one of the alternatives I mentioned. That would play the videos off the website here directly on your TV so it can broadcast the sound to you still. I would try googling your TV brand/model and see if they have a web browser in it. Most do. Then you can go to 599cd.com inside that browser on your TV and you're good to go.

Airplay?

Yeah, sorry. I've got no control over YouTube. You'd have to cancel here and subscribe there.
