how are you guys burning this? i've used nero and imgburn and neither are working

The "fixed" AVCHD editions should burn fine with ImgBurn. That's the program that was used to create the ISO (and associated MDS) files.

Are you using DVD9 discs (DVD+R DL) or trying to burn to DVD5 discs (DVDR)? Hyperspace is sized for DVD+R DL format and won't burn to smaller discs.

If you're still having problems with ImgBurn and you are using the correct size discs, I'd suggest first extracting the files and folders from the ISOs (you can use WinRar). Then, using ImgBurn, write the BDMV and CERTIFICATE folders to your disc in UDF 2.50 format.
