Domination has two requirements: you speak in the language the recipient understands, you are able to capture recipient's eyes, so while in theory it doesn't say anything about broadcasting it over TV its an open way to exploit: Get some low generation Sabbath to national TV station, plant some messages via Mesmerise and watch the country burn.
When you watch TV you don't look at the speaker, you look at his PICTURE, there is no (or VERY limited) connection between yours and his ego/mind/psyche/soul (you need 8 dots in domination to command on far distance, similar dots in Presence), so there is almost no way for the vampire's will to dominate the human one. That is unless... the recipients is really willing to get dominated (as it was the case of the Russian hypnotist Kashpirovsky), but even then personally, as a GM I'd rise the difficulty level sky-high.
In case of Chimestry I don't see why not you can't broadcast your illusions (because they are conjurations - you really summon a picture from nothing, not just make it appear in recipients mind), but hey - they will be again just pictures and in the world where movies are full of state-of-art special effects, your work would not be that special. But again - if something is supposed to work directly on recipients mind (like Horrid Reality) then its a big no, since they are responding to the picture of your creation, not the creation itself.
Powers that work on the mind/emotions of the recipients (dominate, presence, obfuscate) cannot be transmitted via television, because tv lacks the personal contact between minds of vampire and his victim. Powers that actually change something in the physical world obviously can, but they wouldn't be treated the same way as regular tv "special effects".
