 Like HD DVD, CBHD discs have a capacity of 15 GB single-layer and 30GB dual-layer and can utilize existing DVD production lines.In early March 2009, Warner Bros. announced they would be supporting the CBHD format, launching with titles including the "Harry Potter" series and "Blood Diamond", with discs selling for between 50 and 70 yuan (roughly $7.25 to $10.15).According to an August 2009 television story by "TV-Tokyo", CBHD was outselling rival Blu-ray by a margin of 3 to 1 in China (due to heavy advertisement and favored backing from the government).
