Need recommendation on sourcing the SMT capacitors for component video board

I'm running into some snag with component video boards. There are some incorrect traces on the board so I had to cut a few traces and jump a some wires. I'm also running into issues with the SMT caps I'm using. Any particular SMT caps I should use for the 22uf, 220uf and 470uf? Both the 220uf and 470uf are polarized. I switched out the ceramic SMT caps for the thu hole aluminum electrolyte and the board works.

Looks like I'm going to have to scrap the idea of using 1206/1210 SMT cap size for the 220uf and 470uf that the component video boards need. I'm gonna have to go with the bigger radial leaded aluminum electrolytic caps.
