There is no need for an equivalent of EAC for DVDs. EAC's goal is to detect errors on audio CDs, because they miss the error correction codes found on data CD ROM.
DVD-Video are data DVD-ROMs, so they have the proper error correction built-in.
If you get an unnoticed error on a DVD, instead of searching for an equivalent of EAC, backup at once all your vital data before the whole OS crashes on you !
I once got some errors in DVD rips, it was because of my RAM that was corrupted. The only other effect was to sometimes crash the computer after one hour of playing Unreal Tournament.
