US adult film maker Digital Playground will throw its support behind Sony's high-definition Blu-ray DVD format.
"We feel that of the two formats, it's the one that's more future-proofed," Digital Playground's president and founder, who identifies himself as "Joone", said.
Sony's Blu-ray competes with the HD DVD format championed by Toshiba and appears to have amassed more allies in the next-generation DVD format war - including Apple, Panasonic and the majority of movie studios.
But while Digital Playground, known as an innovator in bringing porn to personal computers, has endorsed Blu-ray, it has not yet found a company prepared to mass-produce its films in the new high-definition format.
Joone said companies that replicated DVDs were hesitant about embracing the porn industry and were committed in putting mainstream Hollywood's movies onto the new discs.
Nevertheless, a spokesman for Blu-ray said the endorsement underscored the format's wide appeal.
"It shows that Blu-ray is appealing to film genres of many types," said Andy Parsons, a spokesman for Blu-ray and a senior vice president at Pioneer Electronics.
The failure of the Blu-ray and HD DVD camps to reach a unified standard has set the stage for a war akin to the VHS and Betamax battle of the 1980s. Each side hopes to reignite the sagging $US24 billion ($32 billion) home video market with new players and discs that offer greater capacity and interactive features.
But analysts said the adult film vote does not appear to have as much impact now as it had in past format matches.
