Leonardo/Micro/Esplora <32u4 Does Not Work>

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Arduino Leonardo has no support <Important>
2. Arduino Micro has no support
3. Arduino Esplora has no support
4. All 3 use the same chip

What is the expected output? What do you see instead?
The code compiles per issue 52, but it won't show anything on the display.

Hardware.h was modified according to 
http://code.google.com/p/arduino-tvout/issues/detail?id=52

And all other links on that page. 

The RX Led lights up and remains on. Reading with a voltimeter shows that 
Digital Pin 9 and Ground have movement, but no other pins.

What version of the product are you using? On what operating system?
Newest Beta, on Windows 8

That is the code that compiles.

I have found that the following patches allow the Arduino Leonardo to work with TVout with sound. Since the Leonardo does not have timer 2, this code replaces timer 2 with timer 0 and also adds pin definitions for the Leonardo. The + signs below indicate lines that were added.

I submitted a patch to fix this, but I do not see it applied here yet. You can download a new copy of TVout with these fixes applied from http://playground.arduino.cc/Main/TVout
