Let the hive mind of Engadget get that for you.
"I am looking for a device that will stream sound from one source to several recipients. For example, I want to stream sound from my TV or stereo to my phone or MP3 player that has radio and Bluetooth capabilities. I have looked into radio transmitters and they seem like a decent choice, but I can't find one that uses external power (USB or from the plug) and I would want one with a transmit range of around 50 meters. Thanks!"
Did you purchase a high-quality hardware RAID controller, so you can record up to 4 simultaneous HD streams, at the same time you are streaming 6 simultaneous HD streams out to the Media Center PC itself, along with 5 Media Center Extenders throughout the house?
Did you install HD CableCARD tuners, so you can tune digital HD content from your cable provider? Even if you did, they wouldn't work, as OEM's are the only ones licensed to use them.
Cheap solutions are just that... Cheap... If you want reliability, performance, and out-of-the-box dependability, you're going to have to purchase good quality devices.
I don't have this exact model. I believe it's the model under this one. Sure... It cost some dough... But I will never regret my purchase! I have been totally amazed at the out-of-the-box success of this Media Center PC!
