HELP! 

I need some help in implementing a buffer for a video source. I have tried
using a LM733 but this simple chip has proved too complicated for me to use!
The video source has a Vp-p of approx 1v. I would like to have the buffered
signal have a Vp-p of approx. 4-5v. Does anyone have ANY ideas???

Part of my problem seems to be that the minimum gain of the LM733 is 10, another
problem is that I dont know what the source impedance of my video source is.
I tried using a voltage divider to drive the '733 but I couldnt get that to work
and I really dont know why it wouldnt!

I do have two +5v supplies, and in the configuration I tried I had the '733
powered at +/- 5v, is this the right way to go? Should I be using a different
amp? Please help!!!!

I spent 4 1/2 years in college learning how to be an engineer, and
when I got out I thought that I was pretty smart.  Boy do I feel dumb now!!

Thanks for any help.
