Summary: Bought this to go with a Onkyo Surround System with Receiver. I have not figured out how to get video out of the iPod Touch yet, even getting audio seems to be sketchy at times? The remote does not seem to work either, so it is a very expensive charging dock with connections for playing music through the receiver. Admittedly I have not spent any time trying to figure this out, nor am I willing to.
Summary: The dock works fine although the on screen display is poor quality. My biggest complaint is with customer service. I am new to HDMI and it's been 15 years since I bought my last stereo equipment so I found the manual confusing on how to setup since my dish receiver and TV use HDMI. I sent an email to Onkyo and both their responses were even more vague than the manual. After some trial and error I figured it out with no help from Eric at Onkyo.
Summary: I tried three different IPOD docks with on-screen displays (this Onkyo, the DLO Hi Def home dock and one by Radio Shack). I returned them all and bought an Apple TV. The DS-A3 text-only on screen display is so bad that it has some genuine campy, retro appeal. It's fun in the way that gettig out your old Atari 2600 is fun. My favorite part is the status bar that shows how much is left on the current song. It represents a half-played song like this: [>>>>>>>> ].
Summary: Same product as the DS-A2 except that it can play video. Sound is good with my Onkyo 606 receiver. Remote layout is confusing and has a very limited range. On-screen display is horrible. It looks like DOS back in the 80's. If your not interested in playing video, save your money and buy the DS-A2.
