• DVS 304 A (extron) does not seem to work with atomos (DVI to HDMI) -- there is vertical rolling for some reason (cable issue? copy protect?)
• DVS 304 A (extron) does not seem to work with matrox

notes:

• pulling crystal couldn’t quite reach 31.46KHz
• Orion mis-4220 screen was too picky.
• LG TV RGB input worked fine.
• Eizo monitor works fine.

• hantarex locked its RGB input to 15.75KHz, with blanking in the wrong place

• try 240p with pulse-widths set to 480i)
• matrox did not lock (not surprizing) over composite sync
• sony LCD broadcast screen did not lock properly

• dxc9000 sony camera genlocked to 31.5KHz@60 over composite sync

• dxc9000 will lock to 31.5KHz and still output composite – phase problems and no colour on hantarex though
• will also lock to 15.75KHz and output VGA (N.I.)
• both PAL and NTSC cameras worked, but with different problems over composite output when locked.
• assuming 29.97Hz is needed and PAL not gelling with NTSC
• try with 240p / 480i pulse-widths

notes:

works with Sony LMD-2451w (RGB+Csync)

syncs with Sony BVM-20G1U -- but 31.2500KHz seems to not be supported for some reason

DXC-9000P will not genlock to 576P (official) but PAL yes.

(seems DXC-9000 can output 576p while locked to PAL.
