It will amaze me if someone starts streaming a daily soap on demand. Hundreds of episodes a year; it's daunting.
You can find The Daily Show
, The Tonight Show
, Jimmy Fallon
, etc., on Hulu Plus, and those air daily. True, they do have reruns on occasion, and soaps don't. But a daily broadcast showing up next day? It happens. Just so far, not with a soap opera.
Oh, and I agree with the suggestion to get an antenna. The only issue would be if the OP is used to recording DOOL and watching it later. Then, we're talking the extra expense of a DVR.
Another alternative is watching DOOL episodes from the NBC website
There is no Roku solution, though.
