i'm in the Dallas-Fort Worth market, so i'll play along with this forum game.
Display:
11.1 (RF channel 19.1): KTVT, CBS 11
22.2 (both virtural channel and RF channel): no such station as 22.2 in the Dallas market, there is a actual channel 22, but it's KNAV-LP, a analog station.
33.3 (RF channel 32.3): KDAF, This TV Dallas (will become Court TV this November).
44.4 (RF channel 28.4) : KLEG-CD, Sony SAB (a TV Nework from India).
55.5 (RF channel 31.5): KAZD, VIETV (a vietnamese TV network).
RF channel:
33.3 (virtural channel 23.3): KUVN, Escape
so only 22 is missing as 22 in the Dallas market as there is no ditigal channel 22 in both display or virtural, only an analog LP station showing the shopping network Jewelry TV.
