was the first network attachable, and it’s not a “2nd gen.”
Don’t know why you’d be having stuttering over a wired connection – I’ve never seen that once even with the highest bitrate movies. Don’t know what to suggest other than to make sure you have good cables…
There are huge differences between the Gen 2 and Gen 3 WDTV Live’s. A friend of mine had the Gen 2 model and it worked perfectly. He upgraded to the WDTV Live SMP (Gen 3). He always used an attached HDD. When set up the new one had a flicker on the screen which at times caused the audio to drop for a few seconds.
He used the Gen 2 power pack and the Gen 2 HDMI lead, all of which gave a perfect outcome for his Gen 2 but not for the Gen 3. The HDMI cable was replaced and all flickering, sound drop out problems ceased immediately with the Gen 3.
