I've been using Slingplayer Mobile on my IPhones since the App came out. I'm currently using it on the IPhone 4. It's never been a perfect situation, as I often have trouble changing channels and the picture tends to freeze every so often. Has anyone used it with the IPad 2? And if so, was there much of a difference in quality and speed with it compared to the Iphone other than the obvious screen size? Or even compared to using it with the IPad 1? Also, do you need to purchase the App again for the IPad if you'd already purchased the App for the IPhone? Thanks in advance for whatever information you can provide.
