National Geographic has announced that on March 27, it will release its first documentary in HDTV DVD. The film is called Relentless Enemies, a 90-minute documentary that chronicles the struggle of lions and buffalo in Botswana.
Blu-ray and HD-DVD editions will cost $34.99 each; National Geographic will charge $19.99 for the standard definition DVD.
Last year, National Geographic launched a high-def channel but has struggled to find spots in cable and satellite lineups due to bandwidth limitations. Even though Comcast has signed a carriage agreement with National Geographic HD, the cable operator is only offering NG HD via its On Demand service in several markets.
