        } catch (IOException e) {
            // TODO Auto-generated catch block

        }

        e.printStackTrace();
    }

You’re only appending every other line because you are reading two lines at a time…

while(br.readLine()!=null) // THIS READS FIRST LINE THEN THIRD LINE
{
    line = br.readLine(); // THIS READS SECOND LINE THEN FOURTH AND SO ON
    subtitletv.append(line);
    subtitletv.append("\n");
}

Use…

while((line = br.readLine()) != null)
{
    subtitletv.append(line);
    subtitletv.append("\n");
}
