IMO you have a slim chance of making this name worth something. The only good thing in alot of European countries they prefer a hyphen inbetween words. Only thing, chances are they can afford get their hands on the hyphened .com easily and probably cheap enough to never take second look at your .tv.
Sorry but I still think its worth Mid $XX at most. If the channel thing takes off you may get low $XXX. I also doubt there will be a rush to buy the hyphen versions for long while, look how long it took for the .com hyphen rush, In fact I just let Hi-def-radio.com and high-def-radio.com expire and I sold one for $15, so IMO hyphens have a long way to go before being worth anything.
