ADV7280 I2C

I can write the "AutoDetect_CVBS_Single_Ended_In_Ain_1_YPrPb_Out.py" script to the ADV7280 just fine and everything works fine on my custom hardware.  However, if I modify the script to also read back the register values following each write it does not work (there is no video).  Why?  The register values I read back are correct so I know it's still getting programmed properly.  Also, I noticed that when I run the script on the EVAL board there is about 50 ms between each write. Why?  Is there a minimum time I must wait between each write?
