The RNID has written to all the major newspapers asking them to change their policies on subtitling promotional DVDs. Hunt has also tabled an early day motion in the House of Commons to draw attention to the issue.
"Only The Guardian has a firm policy of ensuring DVDs are subtitled," said Mark Morris, head of parliamentary and European affairs at the RNID. "There's no excuse for not doing it. It only costs a few hundred pounds."
Hunt said: "Subtitling services are vital for more than a million hard-of-hearing people."
The campaign follows a successful bid last year by the RNID and Hunt to increase subtitling on the BBC Parliament channel.
