Also got L634. Turning captions on (now 8-6-1 instead of 8-7-1) no longer turns the captions on. C'mon Dish, I need captions, otherwise I miss about 10% of dialogue on programs with background sounds, laugh tracks, etc. I hear programs like news and Jeopardy fine.
I have L.634 and I have captions; they were turned on before I got L.634. Does this mean that if I turn them off, I won't be able to turn them back on again? Somebody else can try this, maybe; I'm not going to touch 861 for now.
