You can find a patch to fix the Hulu issue here:
The -NEW- HULU fix!
But, one side effect that I believe you will see is that the patch will break your access to the App Catalog, so you will have to make a choice as to which you would rather have - Hulu, or the App Catalog. If you do install the patch, you just have to uninstall the patch and then restart the device.
For install instructions and/or questions on the patch, just read through that thread.
