Question about Televison & Video
I just bought a Vizio 47'' LCD HDTV (Model SV470M). This TV is connected to my cbale Box (Motorola DCX3400) using HDMI cables.
Occassionally, when I change channels on my cable box, the sound on my Vizio tv completely drops out. No problems occur when I use Component cables, only with HDMI cables.
Any clues on why the sound on my Vizio Tv occassionally drops out?

You may have already done this, but check to see if you can change the screen size in the set-top-box settings and set this to widescreen 16:9 to match the tv. You may also have 14:9 as an option too. Also, check your video output settings, this can be changed between RGB, Composite, PAL or NTSC.
Let me know if that does or doesn't solve the problem

the tv has a configaration that conveys the sets focus on both audio and video performance. full hd resolution of 1920-1080 pixels.
hdmi inputs allow connection of the generation of 1080p sources for the systems which offer 1080p outputs
