I just tried viletim's simplified video amp on X'eye, and it's a success!
Here is the amp in case if link don't work:
Output was a bit weird when I was tapping ground from composite video jack, so I moved it to gnd pin of CXA1145, and it got normal. According to viletim, any general purpose NPN transistors will work. I used BC548B and 33 Ohm resistors (what I had).
