Descending into MMPR on the OBRUG 1B. Told to descend to FL200. Then told to descend via as we were passing FL260. There's a discrepancy between the FMC which loads to 'Cross OBRUB at or above 230;' and the chart which says 'Cross at 230.' Once given the initial descent to 200; I deleted the FMC (at or above 230) and crossed above 230 even though told to descend via. Which is correct? The chart or the FMC; and in Mexico was I supposed to cross OBRUG at 230 (as per the chart) even though initially cleared to 200 (and only later) at 260; given the descend via
Air carrier Captain reported procedure disagreements between the FMC and the chart exist on the PVR OBRUG 1B Arrival.
