Hi DTV Mag, I have watched several Soundstage HDTV programs and I don't remember any problems from KCET-HD(LA). I have seen cutting out on other programs and what appeared to be a tape related breaking-up of signal on some other shows. I have had a lot of trouble with my Samsung SIR-165 and have sent it back 3 times for repair. I wish now I had waited a little longer to buy. Sincerely, Bill McBlain
