I have been trying to record PAL 60 and I can tell you that my dazzle cannot do it properly.
Secam will give you colour, however, the picture is wrong. Trying to record anything particularly dark using secam will result in a pitch black screen, whereas NTSC_433 or NTSC_M_J will result in a perfect picture, only its black and white, which is not acceptable really.

I will try a firmware update or something.
