Unfortunately we cannot identify language used on the page (probably there is a mix of languages, too little text or something else), while the claimed language is Russian. Our system also found out that Dvd9.ru main page’s claimed encoding is windows-1251. Changing it to UTF-8 can be a good choice, as this format is commonly used for encoding all over the web and thus their visitors won’t have any troubles with symbol transcription or reading.
