You've got access to the internet - look em up. Some English DVRAB have subtitles in German, some don't. If they do have Foreign language subtitles, it generally says so on the packaging. Have a look at the packaging of the DVRAB that you are about to buy and see whether it says "English subtitles" on it or not. If it says it has English subtitles - assume it has. If it doesn't say it has English subtitles - assume it hasn't.
