DSC Syntax for Binary Registry Key

For the most part the solution suggested by Matthew Whetmore worked… but if the data starts with "00", somehow it is getting dropped. For e.g. for this data:

$  reg = "00,01,04,80,64,00,00,00,70,00,00,00,00,00,00,00,   14,00,00,00,02,00,50,00,03,00,00,00,00,00,18,00,03,00,0f,00,01,02,00,00,00,   00,00,05,20,00,00,00,20,02,00,00,00,00,18,00,03,00,0f,00,01,02,00,00,00,00,   00,05,20,00,00,00,25,02,00,00,00,00,18,00,03,00,0f,00,01,02,00,00,00,00,00,   05,20,00,00,00,27,02,00,00,01,01,00,00,00,00,00,05,12,00,00,00,01,01,00,00,   00,00,00,05,12,00,00,00" 

the first set of 00 gets dropped when DSC adds it to the Registry, and the value in the registry starts with "01 04 …". Looks like a whole left shift going on. The number of bytes stored in the registry is one less the original.

Any one else seeing this anomaly, and possible a fix? Thanks in advance.
