Bug?

[mm1000]

I cant play demo that had big size.

I had demo from cod4:
czar_competo_both_ineyes_doobie_8730122.dm_1 - 24,1 МБ (25 332 933 байт)

Cant add it to clean playlist: "This demo type cannot be added to this play list. You cannot mix differencT demo types. You can only add * to this play list".

Game manager info: cod2, cod4, steam.
