The two stations I receive in my area have CC (NBC and PBS). The odd thing - the PBS station's CC doesn't work when they are passing the PBS National HDTV feed about 7-10 pm, but the simulcast of their analog programming from 7 am to 7 pm has captions working fine.
I am also using a Samsung SIR-T150. Like you, I'm hearing impaired, so I had a similiar question about CC. I heard from some other users that the RCA DTC100 and the Toshiba DS3000 work with CC. No idea which STB won't work with CC.
