All credits goes to huntken, i'm just posting here. Works on my transformer. I'm running Prime 1.7. Original thread here..
1. Delete Hulu Plus if you have it installed already.
2. Delete any backups you may have of it in Titanium Backup.
3. Get Titanium Backup if you don't already have it.
4. Download this file here: and unzip it, there will be 3 folders in it.
5. Place all 3 folders in the sdcard/TitaniumBackup folder
6. Launch Titanium Backup and restore the backup.
And of course I'm not responsible for anything that goes wrong and blah blah blah.
PLEASE NOTE: You can't use "Ad Free" or anything that modifies hosts for this, or the videos won't load.
