The update for the 200(and probably the 300) apparently has been out, but my guess is the auto-update on the 2001 software on the 200(maybe 300 too) is broken or non-existent, so you must force an upgrade (I just learned this, source link posted below).
Open the access card door, press the button in there, it will reset, get the remote in hand, and while it says "Hello, your DirecTV receiver is starting up." press 02468 om the remote, you may have to reset/reenter the numbers a couple times, when it succeeds it will say something like "New software found, downloading.." and the usual percentage bar below, this works on the D10-200, I think it will work for the other D10s as well. It made my D10-200 interface exactly like the D10-100s, I can't speak for the 300, but I'd wager it's the same.
