I have the Generation III. I had a hard time getting up and running, mostly getting on the network, but with Jim's help we got through that. He took time on the weekend to help us work through stuff plus he helped load everything on my external hard drive to the streamer. So customer service is absolutely fantastic. As for the streamer, I'm still in the learning curve, but it's just awesome. On another note, does it make any sense to plug and aftermarket power cord into the extension box?
Yes, depending on the network setup in your home, it can sometimes be a bit of a challenge. The issue is never with the StreamPlayer directly, but getting everything on your network to cooperate. This is especially true on networks with a majority of Apple products.
In this case, for example, the Apple turned on journaling on the USB backup drive. This made it impossible for Linux machines like the StreamPlayer to read the drive. Fortunately, I have run across this before and knew the solution. We just hooked it up to a MAC laptop, turned journaling off and then hooked it back up to the StreamPlayer. This issue is related to the fact that Apple doesn't like system components not manufactured by Apple and throws up roadblocks for non-Apple products. The problem is, most consumers wouldn't know about issues like these and would naturally blame the new device. But we're always here to provide support in this type of situation.
Issues like this are always simple to solve once you are able to nail down the nature of the problem. In this case, we were able to get things up and running without too much trouble.
As for the power cord, I doubt it would make any difference. The StreamPlayer draws very little power, so it doesn't require a mega power cord.
