As long as ponies aren't affected, I'm fine.

there reducing their hours from 24 hour to 6 hour (discovery network will use up the rest of the time)

that wont stop anything for hub, infact it will help them
6 hours will allow for any show they have to have new episodes. plus enough time for reruns, could even throw in a movie.

how i see it its a good idea, it doesn't become a rerun channel with only a few shows to work off of. and if Hub does get new shows they could get more hours by reworking the contract later.
