I'm not sure how long this has been a problem, as I don't often watch Hulu plus, however, on my AppleTV, shows downright fail to start streaming when the device is connected to the E3000 router running Tomato v1.28.7500 MIPSR2Toastman-RT K26 USB VPN but they work perfectly fine when I connect to the router via wi-fi. I tried restoring the AppleTV's OS to factory settings, swapping cables, swapping ethernet ports, testing that my Xbox 360 works fine streaming Hulu via ethernet, tried connecting to a different router/accesspoint on the network, reset Tomato router to default settings, reset NVRAM, all to no avail. Oh, and it worked fine when I plugged the AppleTV directly into the cable modem, bypassing Tomato. Everything else on the AppleTV works perfectly fine, as best I can tell (e.g. Netflix, iTunes store streaming, local LAN streaming, YouTube, Vimeo, etc.).
