VBI injection: it works!!
Track 0 Field 0 WhiteFlag:1 L16:f86767 L17:f81313 L18:f83210
Track 0 Field 1 WhiteFlag:0 L16:f86760 L17:800001 L18:800002
To break that down, on line 11 I have a solid white line (white flag), and on line 16, 17, and 18, I have data that begins with 0xF8. And so on. This is what I was attempting to generate so to have it succeed is very gratifying.
You may notice that there is a little wobble with the white lines in that they are not consistently drawn in the same place. This _may_ be due to the way the AVR handles external interrupts by default. I haven't looked into this too closely yet. I suspect it may not matter at all since the official laserdisc spec does allow for some small variation about when the line is drawn.
