Here's some potential HDMI components that you might end up connecting to your receiver:
1. Blu-ray player.
2. HD DVD player, or a Combo player.
3. PS3 player.
4. XBOX 360.
5. Digital Satellite Cable box.
6. Universal DVD player.
7. DVD player.
8. DVD recorder.
9. TV Cable box & recorder.
10. Blu-ray recorder.
* Hmm... I know there's more, I just can't remember. About any two of those, already mentioned.
Plus whatever else is coming down the pipe, in the future.
** HDMI is here to stay, and it will just keep expanding.
Cheers,
