• عدم حذف تگ‌ها ، گاها برنامه نویس‌ها از تگ هایی چون Bold,italic,underline,color استفاده می‌کنند که معدود برنامه‌هایی آن را پشتیبانی کرده و تلویزیون و پلیرها هم که اصلا پشتیبانی نمی‌کنند و باعث میشود که متن روی تلویزیون مثل کد html ظاهر شود
• بعضی جملات دوبار روی صفحه ظاهر می‌شوند.
• تنها یک فایل را در هر زمان تبدیل می‌کند. مثلا اگر یک سریال چند قسمته داشته باشید، برای هر قسمت باید زیرنویس را انتخاب کرده و تبدیل کنید، در صورتی که میتوان دستور داد تمام زیرنویس‌های داخل دایرکتوری را تبدیل کرد یا چند زیرنویس را برای این منظور انتخاب کرد.
