I posted earlier but I didn't give enough details of how it works for me. I watch HOBO GO on my iPad everynight with no problem, plugged into my reciever in my theater room with no extra stuff except the HDMI adapter I got from Apple.
Here are my steps:
1. Plug in iPad using the Apple HDMI adapter (which is already attach to my reciever via an HDMI cable)
2. Launch HBO GO and find what I want to watch on the iPad and make sure iPad view is horizontal.
3. Close HBO GO using the iPad Home hey
4. Rotate through input source of my reciever till I get back to my HDMI input (example: my source is HDMI 2. I keep clicking HDMI input till I get back to HDMI 2).
5. Wait till I can see my iPad desktop on my TV screen
6. Click HBO GO
7. BOOM! Audio & Video are on my TV screen. Click play on the iPad and enjoy!
Works every time! Not supported != Not available.
Equipment:
HDMI adapter from Apple
Cheap HDMI cable from Wal-Mart
Receiver: Pioneer VSX-1120-K
Reason Why I do It: My local cable provider does not allow me to view earlier versions of certain series from HBO, but HBO GO seems to have it all.
