I used to get WABG-DT over here until March 17, 2006 when KARK-DT (Little Rock) increased power. One thing, about WABG was they were passing DD 5.1 audio while KATV-DT [ABC] in Little Rock (only increased power last fall) still only broadcasts 2.0 audio. E* and D* HD channels are often compressed and that accounts for the lackluster quaility.
WXVT has potential with its CBS affiliation, but present ownership and management IMHO doesn't help things. Although i generally hate multicasting, a dual CBS/CW digital signal could do wonders for 'XVT. Too bad WABG lost CBS in the mid 1960's over WJTV's objections. KTVE (NBC) has problems of their own, plus its not that local of a signal in the eastern part of the G/G DMA. WLBT cast their lot with VHF and damanges any fringe coverage to the north.
Don't get hopes up, its only a bottom 25 market.
