Will a Blu-ray player work with a normal television?

By normal TVs, I assume you mean regular resolution TVs. Blu-ray Players require High Definition output, and that means you need to play Blu-Ray movies on HD capable television sets.

Even on my DIGISTOR external Blu-Ray drive, I still need a computer monitor that is HD/HDCP capable, so that I can watch Blu-Ray movies on my computer system.
