i tried HULU live and while i liked it overall, the dvr aspect of it was wonky. seemed a lot more confusing then need be. especially if you're accustomed to a "guide" view where you find the channel, find the show and time, hit a button to record it. HULU is more "show" based, like you said, vs a more time orientated DVR set up. works great for shows but it was a little harder to figure out for recording sports. the first NU game i recorded, i literally COULD NOT find it. the only way i eventually found it was through a random link on the HULU interface that popped up cause we had just happened to watch an NU volleyball game the night before. it was weird.
I'm not that crazy about the PSVue DVR interface for recording sports either, but i found it easier then HULU.
