We have TWC here in charlotte and I have a new Vizio 32" HDTV. We swapped out the old box for the 8300HDC and connected via HDMI. This was Friday.
Everything worked great, excellent picture on HD channels! However last night I was watching NFL on NBC and the screen blinked/flashed like a camera flash a couple of times. The DVR stuttered a bit too.
No power issues that I am aware of occurred.
I am new to all this and apologize if I ask the obvious....
