The Blu-ray player comes with composite video cables which should work for any tv made in the last 15 years or so. But, as noted below, you will not see any notable video quality improvement without an hdtv.
I have a HD TV, although i don't have the service of HD. It works fine for me. So, sorry i can't give you an exact answer. Did you read the description on the player? Try googling it, and possibly you'll get the info you need from another source.
