Homemade BluRay not converting to DVD

Hello,

Thank you in advance for your help.

I've just started into this world of Bluray, and I have this situation:

I have _several_ Bluray to DVD converters (which is what I want to do-I'm on Windows 7 x64, BTW).
When I Bluray to DVD a commercial Bluray disk, everything works fine on all of the converters
However, when I try to convert a homemade bluray disk to DVD (which is what I really want), all of the converters tell me there's something wrong or invalid with my homemade bluray disks even though PowerDVD, VLC, etc, etc will play them just fine.

I looked at the structure of the homemade Bluray discs, and they generally seem the same as the commercial ones.

So, either I've got to find a way to convert my homemade bluray discs to DVD or, take the several m2ts files in the Streaming folder and smash those all in to one DVD. I'll take either solution--I just need a solution that works

Thanks, in advance.

Max
