Are the lines/field, REFCLKS/line independent of the video source type? Should they consistently report the same numbers?
I am using sync on green. It is detected as SOG. TVP7002 also detects clocks per line and lines per field but the lines per field are not detected consistently. Most of the time the registers report 990 lines per field, which is correct, but every now an then they report almost 3000. Is the TVP7002 being fooled by the video source or by the settings on the other registers (clamp, PLL parameters, etc.)?
Wondering if this effect on the TVP7002 is causing the vertical drive to fluctuate. TVP7002 is not reporting all vertical drive pulses.
