'Rachael Ray' isn't produced by ABC. 'Live with Kelly and Michael' on the other hand is produced by ABC. However, in some markets the Fox O&O clears the show. So, ABC as syndicator has gone with the Fox O&O clearing it over the ABC affiliate, which I find somewhat interesting.
Back on Philly, it's know it's unlikely WPVI will ever veer away from WABC in lineup programming since ABC likely wants to keep them aligned for whatever reason. Even though some things can work better on WPVI including local AM programming and 4pm news, and the two markets are different in general.
Yeah, it'd be more of an issue moving LMAD to WPSG, but CBS owns both stations. I remember NBC's game show Concentration appearing on one of the UHF stations WTXF in the past. I think the ratings on LMAD are poor, but I haven't followed it extensively.

Speaking of Rachael Ray:
Rachael Ray still has Harpo as Production, but she didn't guest appear with Oprah on her final season, anytime after Rachael went syndicated really, or appear on OWN, or her magazine as far as I know. I wonder if the two ladies are just keeping their agreement but just for business purposes.
