I have 1 hdmi input on my TV. I use this with my cable box. I just got a blue ray dvd player and want to use a hdmi cable with this also but there is no other impu on the TV. Any suggestions?

You could use HDMI for your Blu Ray, and Component for Cable or a switcher:

You can get an HDMI switcher. It's a box where you can plug multiple HDMI inputs and connect it to the TV's HDMI input.
