i am not entirely sure, but can say that we have an old dvd unit hooked up to ours. we have yet to figure out how to sync the remote, but that has more to do with the age of the dvd player than the tv. we have to use 2 remotes. otherwise it works fine.

Yes. It has standard coax input along with 4 hd inputs

yes

I would say yes, as we hook up our Wii to it using the A/V outputs of the Wii to the composite inputs...

How old? :-)

You can - TV has composite connections (Red and White audio and yellow video)

The VIZIO 42" Class LED Smart HDTV has composite ports that can be used to connect an old style (RCA jacks) VCR to it.

Try going into the audio options and testing out different pre-sets or adjusting the EQ manually.

Check and see if the speakers are set to "surround" instead of "stereo". Or vice versa. Then just make it the other. That should solve it.

Try playing around with the equalizer or just turn off the surround sound i got used to it after a few days so it doesn't bother me anymore

the overpowering music in the new movies is one of my pet peeves!
there are several audio options for this TV. play with them a bit and you may find something that suits you.

You can go to the audio settings in the menu and set to virtual surround which creates a clearer distinction on any dialogue.

The only way I can think of would be to connect a full 5.1 surround system and then jack up the center channel and turn down the surrounds. there is no other practical way to do what what you would like. Problem lies in the source material.

No, but there may be a way to download that one.

No.

This vizio TV does not of the DirectTV App.

As of 12/26/14 I did not see that offered as an app.

No it does not

No, the direct TV app doesn't come with the TV.

I'd say try any of the Pioneer soundbars or soundbase systems, or the Yamaha YAS-203 soundbar.

These systems give you excellent sound for the price. Sony's recent stuff isn't bad either. I would check review sites like Cnet or the Wirecutter for more thorough reviews and recommendations.

Hi, I know what you mean with regards to the sound of most TV's available (some would say that none of the TV units have very good sound quality). You can simply brows the net and find sound cards that will serve your needs. For instance Sears has a Sony sound bar with sub-woofer for $84.99 and Best Buy has a Magnavox sound bar with sub-woofer for $99.99. both will serve your needs well but in the end it's your ears that have to make the decision so go to the stores and hear for yourself wich one will best satisfy you.
Hope this helps

The Samsung HW-H450 for about $200 is what I have it it provides excellent sound and connectivity in my BR.

Try setting the audio to surround sound first, that is what I did and love the sound, plenty of volume

It sounds like your t v is not picking up the wifi signal, may have to go back to set up and try again. Mine picked up my signal right away and was ready to go.

We had this problem once too. Have you got a password on your router? We don't and when I had called Tech Support, they said that would help. But when I had talked to them, they told me to unplug the TV, and hold the power button down (it's in back of the TV on the left side) to recycle the TV. They are very good about helping you get something like this fixed. It's probably something simple.

I connected the usb cable to get better connection, no problem with connecting apps, if this is possible

It depends on the plugs that your surround system has.

Yes, this product is compatible with a surround sound system.

Ac wifi routers should be able to accomodate bgn type connection speeds, check with ur wifi router vendor.

If you are talking about power cord, Yes

QAM stands for quadrature amplitude modulation, the format by which digital cable channels are encoded and transmitted via cable television providers. QAM is used in a variety of communications systems such as Dial-up modems and WiFi. In cable systems, a QAM tuner is linked to the cable in a manner that is equivalent to an ATSC tuner which is required to receive over-the-air (OTA) digital channels broadcast by local television stations when attached to an antenna. Most new HDTV digital televisions support both of these standards. QAM uses the same 6 MHz bandwidth as ATSC, using a standard known as ITU-J.83b. Try hooking up you TV directly it may or may not work, it depends on your Cable provider but there's nothing to loose if you try.

QAM is a modulation format used in some TVs, it's a
form' of how a TV signal is broadcast. Doubt it would do you much good as most all cable companies are now encrypting the sigmal to defeat the QAM receiver.
