It's the last module 'BHG_VIDEO_DPDC_BRAM', starting at line 1319, right at the bottom.

That's not a true dual port RAM, as it only writes into one port and reads off another one. Xilinx calls that Simple Dual Port RAM, and there is a module for that too: XPM_MEMORY_SDPRAM, but your code might just work as-is. Leave it like that for now, once nockieboy completes the port, he can verify if it works or not.
