I'm having a slightly different problem with HBO GO. I just got an HDMI adapter for my iPad that I'd like to use to watch HBO GO on my TV. The adapter works well to mirror my iPad and play movies using TV Out. However, when I start playing a video using HBO GO, the app says that it is using TV Out for playback, but I get no video (only audio and--if I turn it on--closed captioning).
Interestingly, when I scrub to different playback locations, the video pops on for a second or two before disappearing again. Something similar happens in the following scenario. If I unplug the HDMI adapter, I get video back on the ipad, and if I plug it in while the video is playing, I get mirroring for a second, then the app says that it is using TV Out, at which point the picture expands to higher quality, but then it goes blank again after just a couple of seconds.
Anyone have an idea what's going on?
Thanks.
