Cardio Suggestions Please

I have the Billy Blanks Videos, P90x Videos, Hip Hop Ab Videos and the elliptical.  I am getting kinda bored with these.   Can anyone offer any suggestions on some cardio I can do inside.   Maybe a different video or something else.  I have plenty of cardio I can do outside when its not raining or hotter than heck (100+) .  I am open to all suggestions and greatly appreciate them all! Thanks in advance!  

New girl on site

Hey everyone! I am new to the site.  I need to lose 64 lbs.  I am going to try my best to lose it.  I had gotten to the point where there was no hope left, felt like giving up and throwing in the towel.  I am really hoping that there are some people here that will be there for me and help me thru my struggles and I would do the same for him/her.  I know I can do this, I just know it.
