With Hulu+ you can stream most network shows within 24 hrs with the exception of CBS with on demand commercial free. You don't even need a DVR. I added CBS commercial free with my Hulu+ subscription and I get all the shows I normally get OTA commercial free and no DVR needed. Live news is the only thing I watch OTA now and even that can be streamed free in most locations with local TV apps. CBSondemand even includes live CBS stream.
EDIT: I don't have Hulu live as I see no need for it.
