DWDB-TV signed on for the first time on August 27, 1995, under the on-air brand Citynet Television 27 (or just Citynet 27). The station was programmed like an independent station—GMA intended Citynet 27 to be its main outlet for imported programming (particularly from the United States), freeing up slots in GMA Network's schedule for more domestic productions. Aside from an English dub of the Hispanic telenovela Ka Ina, the only locally produced program on the station was Citynet Television News, a flagship TV news show produced by GMA News and Public Affairs.
However, by 1999, the costs of operating the station in this format were becoming too high for GMA. As a result, DWDB was turned into a music channel under the interim branding EMC, the Entertainment Music Channel—which was also the country's first locally operated music channel. A few months later, GMA reached a deal with Asian broadcaster STAR TV to allow DWDB to be a carrier of Channel V Philippines, which took effect December 19, 1999. GMA had already aired selected Channel V programming from its international version (which made the former VJ's and Filipino descented Trey Farley and Joey Mead familiar to viewers of DWDB). This arrangement did not last long—a stake in GMA was recently purchased by the Philippine Long Distance Telephone Company, who already owned MTV Philippines through the Nation Broadcasting Corporation and its parent company MediaQuest Holdings. This conflict of interest, along with the increasing competition from the MTV affiliated network, led to the channel signing-off on July 25, 2001.
