4. Check online: Some movie databases and websites provide information about the languages and subtitles available for DVDs. You can search for the DVD you are interested in and check if English subtitles are listed.
5. Ask the seller: If you are buying a DVD online or from a store, you can contact the seller and ask them if the DVD has English subtitles. The seller should be able to provide you with this information.
