Mine arrived today and worked like a charm right out of the box. Watching both Live TV and Recorded programing worked without a problem. When iPhone connected to the receiver it automatically went into dual mode and when disconnected automatically put the receiver back into single mode. I'm just waiting for a scheduled show to start recording so I can see what happens then whey I try to access the DVR.
- 3G connection the picture quality is certainly watchable but clearly not anywhere near HD quality. More like low quality YouTube video.
- WiFi connection displayed a much better quality picture although I still wouldn't call it HD.
The only problem I experienced was my guide on the iPhone was missing some channels/shows. This has happened to me in the past as well and it usually clears itself up by time I use the app again a couple days later. I'm guessing this is just one of those connection issues I have heard others mention.
I can manually enter any channel I want and it works just fine so not a major deal but still would be nice to have a complete guide showing all available programing. For example MSNBC wasn't even on the guide on my iPhone..
Others have asked about USB hubs. I'm currently using a non powered one and it works just fine. My external hard drive has it's own power source. I'm guessing if your drive doesn't have it's own power source and has to share with the Sling Adaptor your mileage may very.
Over all I would highly recommend and you certainly can't beat the price! FREE
