So I’m downloading Fallout 3 on my Xbox one I bought the digital version and the dlcs but...

The Known Experience Concerns states that the retail non-GOTY DLC discs should work if I have the digital version of Fallout 3, which I do.

"Fallout 3: You will only be able to play disc based DLC for Fallout 3 if you also own the digital version of the game. Disc based DLC includes the Broken Steel and Point Lookout disc and the Operation Anchorage and The Pitt disc. This restriction
does not apply to the Game of the Year Edition."

So in my case, it should work but does not. The DLCs are downloaded but not recognized when they should be.

I have a fallout 3 problem myself. I have fallout 3 GOTY, my game disc does not read well on the one but the 360 it reads fine. the dlc disc of fallout 3 is fine and can read on the one.

Because I preordered fallout 4 I got fallout 3 game itself for download but no dlc with it so I put in the dlc disc and the console installed the dlc no problem. I run the game and check downloads and none of the dlc shows up at all not even when I load
the game but it's on my game manager as installed...

I also bought the digital version but I received the code for Fallout 3 in a couple of days.

Hey there, Gutsy! Fallout 3 disc-based DLC isn't going to be recognized unless you have the GOTY edition. You will need to have all of the DLC in their digital form in order to play them on the Xbox One if you do not have the GOTY edition. We have this listed
in our Known Experience Concerns thread (which you can check for other known issues, if you would like!).

As for it only downloading in French for Broken Steel, is this for the digital version? If you don't have the digital version, you will need to purchase that version and download it. If you're still getting it in French, or if you already own the digital
version, please fill out the survey at the bottom of
this sticky so that the right people can look further into it. Thanks for understanding!

My problem is solved. For this specific instance, I was playing Fallout 3 GOTY edition where all the DLC are downloaded when you put in the disc. After reconnecting to the internet and putting the disc in, the download for the missing DLC initiated.

Glad it's solved. It's the same for most DLC....the disc generally contains the base game and any DLC is digital and so should download on install
