Thanks to the DX hobby, I've seen a few of the more unusual affiliates in other markets.
KALB Alexandria LA was a NBC affiliate during the analog era and still carries that on their primary stream (5-1). But KALB also multicasts CBS via a full HDTV stream on 5-2. Another multicast affiliate with 2 HDTV streams is WGBC Meridian MS which carries FOX on 30-1 and the legacy NBC affiliation on 30-2. Most of the other stations with dual network affiliations via DTV have a Big Four and a netlet or Spanish language (The CW, MNTV, Univision, etc)
Closer to home, FOX is in SDTV via the -2 subchannels of WABG Greenwood MS (a primary ABC affiliate on 6-1), and KTVE El Dorado AR on 10-2 (a stretchovision relay of "sister" station KARD West Monroe LA)
