I understand that you want to know how to get a refund for the SlingPlayer for iPad application.
Since these products are available (and are sold) only at the App Store, I encourage you to contact them in order to know how to request the refund. They will provide you with all the related information, according to their policies:
Hope this helps.
I too purchased the iPad App before I realised that my brand new Slingbox (SlingBox Pro) was not compatiable (DoH!), What is the process to request a refund, you say go to APple, Apple say got to the Developer (you guys !) - Catch 22.
Can you give me anymore advice please ?
