What data is in LOTR EXT R1 subpictures 2-5?

I am working on region 1 Lord of The Rings quot;Fellowship of the Ringquot; extended version and want to know if someone can tell me what the data is in subpicture streams 2 thru 5. They are labeled as English in IfoEdit, but they are not selectable from my standalone DVD player...

I only keep stream 1, and all of the subtitles appear to be there, but I am just curious about 2-5...

Thanks,
Kevin
