That's such a dumb, lazy move Universal Pictures. Much of the hoopla when DVD first came out was about how easy it was to lay a subtitle track down, much more so than on video. So what are the hard of hearing supposed to do? Just not watch it? That's more than a bit discriminatory, Universal. And it's not just the hard of hearing. My wife speaks good English, but she's not a native. She loves the program, but simply can't keep up with the rapid-fire speech, much less the medical jargon, without subtitles to fall back on. Major boos to Universal, and lost revenue too. I shan't buy them without subtitles. Now see what a dumb move that was Universal?
Shame. I'm also no native English speaker, and the subtitles are a great help to watch the show in original language. The German editions of season 1-4 all have subtitles in German and English (and, of course, English soundtrack), so it might be a possibility for you guys. However, the German DVDs are more expensive.
