well let me say I've had both, have a dishnetwork 942 dvr now and I'm thinking of switching back to TWC myself. As far as quality dish has the edge imo,but TWC is going to be switching to all digital channels in our area sometime this year(I HOPE).The SA8300HDDVR, that TWC has is ok,has ondemand features the 942 doesn't have,but you can't take out channels in the program guide that you don't watch like the 942. I may wait till TWC switches to all digital and way my options then. why are you wanting to switch if Ican ask
