Hi Mohrt,
I've just spent a bunch of hours researching these lights to buy them for myself. I think I'm going to get a 120/meter 3538 strip, and also a 60/meter 5050 strip, in both cool white and bright white, to see which I like best.
In reading the specs on the 3528, 120 diode/meter strips, they draw .8 A per meter. I see you were using a 1A power supply (I think for your whole setup). Did you ever try a larger wattage power supply? You were very undersize on your PS if I'm reading the specs correctly.
I'm going to get one of these power supplies I think:

I also fooled around with my camera, standing on the table and seeing if it can get it from over head. If it did, I want to incorporate the camera into the light design.
So far, its a no go on the camera. My ceiling is 6' higher than the bed of the table. It takes a fish eye lens on my setup to see the whole table, and I'm not sure I like the look. I have a couple other wide angel lenses on order, to see how I like them.
An overhead shot of just half the table looks great. I wonder if I can have a camera at each end of the table, and combine their picture in my capture software.
Another option I'm thinking of in my case, is to mount the strips directly to the ceiling, instead of in a box. This would be for an aesthetic sleekness. I could have an acrylic channel that just cover the individual strips. So when you look up, you see just individual frosted glass looking strips. Not sure if I will go this path or not.
