Dvr-107 vs dvr-107d

I’ve searched the forum and was unable to find the difference between the two.

thats because there isnt 1
only the 107-j /107-xl r different


Newegg for example sells it as DVR-107D and Mwave sells it as DVR-107. A bit confusing. I thought the DVR-107 was the oem for the A07 and figured the 107D must be an oem for something different.
