I have a Pro-HD hooked up to my Vip 722 (component).
I am a Dish Network subscriber, and recently checked out their Remote Access area since they've added iPad support amongst other things. I noticed under the Preferences tab that I could go to Recievers and Manually add the Pro-HD. Low and behold, after that I could then click on a previously recorded TV show and selcet "Play on TV" (which had been there before) or "Play on Web" IE8 only - or with Chrome IE tab - I will see if the iPad works for this tonight (which would suck because I just bought the $3- iPadd SlingBox app).
When you manually add your SlingBox Pro-HD and probably Solo-HD, you'll need to input your SlingBox ID (a very long number) and SlingBox password.
Anyways, this is something new that I have not read about at all. I do know that if you purchased the Sling Adapter (grill-looking thing/ USB connection) to your ViP 722, this feature would show up on Remote access (Web browser and iPad).
Just wondering if any Dish subscribers out there have discovered this too?....
Edit: It is a $30 iPad app, not $3.
When I went to my Remote Access later last night I noticed that the DVR/ SlingBox settings now have an option for TV input and output (TV1/ TV2).
I can now use the free Dish iPad app to watch TV2, or use the $30 SlingBox iPad app to watch TV1. The only caveat with the Dish app is that once you try to watch a recorded show, it also takes over TV1.
