English subtitles are good for somebody who likes to watch the movies in English but finds it difficult to follow the accent as some foreign English accents can be quite challenging especially for an Indian viewer. The best solution would be to have optional subtitles which the user can have the choice of switching on or off from the STB settings just as the language feed can be switched similar to DVD or BluRay. I believe this solution of optional subtitles is being worked upon by the DTH providers as per some reports.
