Quick overview of DOXTV around the net brings me to the conclusion of no value. My personal opinion is from a domain real-estate view you would get $regfee-35 for just the domain name no website. I highly suggest you come up with an idea and try to maximize the profits to the extent that you could get a high $xxx amount for it.
i have many good 3 letter LLLtv.com . but looks like they do not worth anything except if you lucky to get a company interested your name. otherwise, hard to sell at good price.
