BLAKES 7 EPISODE DVDs
The Blakes 7 episodes are available in PAL DVDs through Amazon.com UK. For people in the US, these DVDs will play on your computer, but NOT on your TV. The only safe way to play them on your computer is in an external DVD player devoted ONLY to PAL DVDs. When you put a DVD into a DVD drive, it's able to tell whether the DVD is PAL or NTSC (US standard) and play the DVD correctly. But it will ONLY SWITCH BACK AND FORTH something like 7 times. After that, it stays on whatever was played in it last. So if you only have a single DVD player, you could get it stuck being ONLY able to play PAL DVDs. But you're safe if you attach an extra DVD player to your computer and use it exclusively for PAL DVDs.
