This may be old news to some folk but it was new to me... seasons 1 and 2 of the original OUTER LIMITS have just been released in boxed-set form. Available from www.dvdboxoffice.com
(a personal favourite for Region 1 -- Canadian-based site with low prices and free worldwide shipping) and www.playusa.com
(can be slightly more expensive but still cheaper than most, also free shipping), no doubt along with loads of other sites that I haven't tested out.
If your DVD machine isn't multiregional, check out the hacks section of the DVD Reviewer site. A simple code entered via the remote control removes the region coding on most machines with no damage or negative effect on performance.
