Thanks for posting to our Forums! I can see how not having the option for HD mode will cause a problem. With this issue I would usually advise you to remove the application to the iPad, and then install the application again, there could of been a corruption on the application when the update was installed. You will not have to pay for the application again as long as you are using the same iTunes account that the application was purchased on to begin with.
I would also make sure your Slingbox is up to date on the firmware.

I have tried uninstalling the app and re-installing it. That had no affect on the issue.
I was under the impression that the ProHD automatically checks for updates, but I did check the firmware/reset my ProHD and it also had no affect.
Any other ideas?
Given that it works on my laptop, it really seems like an app issue.
