Do you have to have an HD TV to play HD dvds?

to get the best quality, yes, you'll need an hdtv. otherwise it will just look like a normal dvd on your normal tv. you should invest in onan hdtv before the hd dvd player anyway (especially until the hd dvd vs. blu-ray thing gets sorted out).

You can watch them, but the picture quality will be very similar to a standard DVD. But it's still good to have in case you ever get an HDTV.

kind of

You can play HD DVDs and Blu-Ray discs on a non HD tv, they will look like a regular non HD disc. No problems.

i have a HD tv.and movies and tried it on my grannies it didnt work so im guessing..... no

THE HD DVD PLAYER CAN PLAY NORMAL DVD'S. BUT TO GET THE HI DEF PICTURE, YOU'LL NEED AN HD TV. BLUE RAY PLAYERS ONLY WORK ON HD TV'S WITH 1080P. BLUE RAY IS A RIP OFF. STICK WITH NORMAL HD PLAYERS.

if you have hd tv than you can see the full effects of hd-dvd
