The only foreign series I watch is BBUS, which I download the episodes of using torrents.
As well as that,
http://realitytvfan.org is a great site that has foreign BB's uploaded on Veoh.
There's also a youtube account that uploads BB US episodes:

I don't know how you can download other foreign versions but I'm sure you could get them on torrents as well, and I'm sure other posters will be glad to tell you how they get theirs.
