SPLIT-SCREEN MATCHMAKING PROBLEM

Hi, I’m a GOLD member who plays Halo 3 splitscreen (2-4 players) online with a single LIVE membership; the others select an Xbox Live GUEST profile and we can play social playlists with no problem.
Just today I tried to do the same in Halo Reach, but I get a message like Some player doesn’t have the required content

I have never played Halo Reach online, so maybe the options are different.
Any idea?

Thanks.

P.s.
I play the ODST disc of Halo 3 multiplayer, so I have all the maps.
In Halo Reach I don’t have DLC.

Only ONE playlist in Halo: Reach is DLC required, just avoid that playlist.

I believe if you read the message carefully, it will say you don’t have the RECOMMENDED content, not REQUIRED.

It’s a common misconception, but play anything but Squad DLC and you should be fine.

Also, some playlists actually don’t support more than one guest, Squad Slayer supports up to three guests and so does Living Dead I believe so try giving those a go.
