How are the SDH subtitles on Pirates 1,2?

[MMhardKy]

I was very dissappointed that there are no normal english subtitles on Pirates 1 & 2, as I really need those to understand spoken english in movies completely and the idea of having too much text on the screen describing every sound is not very pleasant. My question is how much text is in those SDH subtitles? Is there really every sound transcribed or just a musical note before the text line when somebody is singing etc.? I have only seen SDH subtitles on a DVD a while ago and I can't really remember how it was done.
Please understand that I'm not against SDH subtitles, I'm only dissappointed that the only version that is aviable with english 5.1 PCM does not have normal english subtitles and the german version (which will probably have them) will have only German PCM, english only in DD. (so I have heard). If the SDH subtitles are not that different from normal subtitles, I might order the US version.
Thanks
