It says both 123 and 124 in HRM, it would seem we can't go below 124 (from a decision, as HRM says, to save hardware buffers (but still has the figure 28867 everywhere). 28603(.99)Hz is the max PAL sampling rate then, whatever HRM says. And odd and even scanlines are both long, whatever HRM says.

So: 124.

Edit: I speak of PAL only.
