ADV7393 pixel compression in the square pixel mode

We are using the ADV7393 connected to a TI DM648 DSP to output NTSC video.  When put the part in square pixel mode and output video, we get output video that is squished horizontally by about 14 pixels or a little over 2%.  Do you have any information on this?  We are following the setup in Table 79 from the data sheet.  I have verified my clock at 24.5454 Mhz.  I don't see any other parameters that could result in this scaling.  Any ideas?
