I dont know if this has been discussed before but i got Hulu, Netflix, youtube and many other web channels to work on the HDI prime 3. I used a simple application called playon.
You get a 14 day trial and it $40 after that. So far its been working great and the quality is good enough to watch...! its very easy to setup your server under windows 7. Once your server is setup you can browse your network on your Dune menu. There you will see your playon server listed with all your channels you enabled to view. I know it isn't a native Hulu or netflix player app, but its better than nothing. Playon also works with Iphone, Ipad, android, PS3, xbox360 etc etc. There are also other applications that work similar fashion.
You can also try the following.
Im sure there are many more out there but this playon thing is doing everything i wanted to do. Both Playon and tversity have a huge fan base, so finding pluggins to add to your experience shouldn't be a problem.
Sorry if this was discussed before, i just thought i share my findings...
