Shou works wonderfully, esp 5.9. Its really nice having the screen recording in case something goes wrong. If you are techy, do the jailbreak and you won't have to worry about apple closing the certificates from the app and you will always get the most latest version of Shou.
What part doesn't work? Have you tired deleting the apps from Cydia, and grab the latest from the repo. You should be on version 5.9. Also, delete the Shou.tv app, and it should prompt you to redownload the player once you launch the Shou app for the first time. Good luck!
I had to sign in once with WiFi into the TV app which indeed is annoying. Then I just killed the Shou TV app, and the Shou screen recorder worked fine without being connected to the internet. I am 5.9.
