Audio Problems When I have a comcast/motorola cable box connected thru the component inputs the sound will intermittently either sound scrambled/garbled or has a loud tone. This problem also occurs with a dvd connected in the component inputs too. Also if you select 720p or 1080I in the service menu on the motorola box there is a loud popping sound thru the tv speakers even if the audio input cables are disconnected. It seems the popping is from the Y input. If you switch the resolution to 480i or 480p it seems to go away. Any ideas where the problem is?

Hi ccraigo
To answer your question;
Your motorola will connect directly(not through the dvd) to the tv set into one of the input ,(preferably using hdmi or component cables for hd) and the dvd will use a different input,
All you have to do then is switch between which one you want to watch.
Hope this help Cheers

Your dvd recorder only has rca, red white yellow inputs it wont allow you to record in HD, although you can play your comcast box any hd, regular digital through and record. Hook up the comcast box if HD through preferably HDMI if not get one from comcast. The HD box is the only box that allow HDMI, component and regular RCA and some RF out. This way you can play HD to your set but also record through RCA or RF again will not allow for HD record unless its TiVo. Hope this helps

If you only have the comcast receiver and a TV, take the input (wire from outside the house or outlet on wall) and screw that onto the input of the comcast receiver. Take another wire (or RCA, component connecters or whatever means the box and TV provides) and go from the output of comcast receiver to the input of the TV. Set the TV input mode (on the TV itself or by the remote) to whatever mode you hooked up the cables to (video 1, aux, video 2, etc) and you should see a picture. From there use the comcast remote to change channel. If you use the round cable (rg56 or rg59) you will not need any other connections between the TV and the box. The video and audio are broadcast on the same line. If you use RCA (yellow red white) connectors, yellow is video, white and red are audio) you will need all three wires from comcast receiver to TV. I hope this helps and good luck!

if the Comcast cable box has an HDMI output, it should connect directly to one of the TV HDMI inputs. Then connect the LG DVD unit HDMI output to the second HDMI input of the TV. Use two HDMI cables. Do not buy the expensive Monster HDMI cables. If you have already done so, I recommend you take it back for a refund, then buy the low cost HDMI cables which will work just as good and then you can bank the savings toward a new Porsche Boxter!! Now we have the video connected from both the cable box and the LG system.

Now--what do you do if the cable box does not have an HDMI output--just use its component output and your component cable (red, blue and green) to connect to the TV component input. This will still get the video to the TV and good HD pictures. Hum--do you have an HD cable box? You did not say and I just assumed that you did since you got the HDTV. If not, let me know with a follow up question and I will assist in that area further.

Now for the audio connections--The DVD player will not need any connections since it in the LG unit. The sound will come out the speakers when you start playing the DVD. The cable box is where we get the TV audio to feed the LG unit. If the cable box has an optical output, use an optical cable (again the low cost one)and connect to the optical input on the LG.
This will get the TV audio to the surround system. If no optical output, use the red and white (left/right) audio connections and connect to one of the two the LG audio inputs. To hear TV audio on the LG speakers, just switch to that input or the input associated with the optical input.

To watch DVDs, switch the TV to the HDMI input to which you connected the LG unit. For TV, go to the other HDMI input (or component input).
Switch the LG to the audio input to which you connected the cable box to get TV sound.

Hope this gives you food for thought. If so, and you have more questions, just come back in with a follow up.

Could be a sync calibration issue. Try to divert the TV sound to another input source on the Hometheatre system if possible, if it is a go then maybe the TV audio needs to be recalibrated. Make sure TV audio setup menu option has not changed also.

There are three options:

1) Connect the Tivo using the coax output of the cable box into the cable input of the Tivo

2) Exchange cable boxes with your cable provider for one with composite output jacks. It may require you to use a Motorola box that isn't High def depending on what your provider has. I know Comcast has a Motorola HD tuner that has composite outputs as well as component.

3) Upgrade to a Series 3 Tivo. Those units are designed for High Def. Use HDMI cable hookup.

Connect the HDMI outputs on your various components to the HDMI inputs on your receiver. Connect the HDMI output on the receiver to the input on your TV. HDMI incorporates digital audio, so no need to buy optical audio cables. If your receiver does not have HDMI inputs for all your components, you will need to make a choice. HDMI = Best, component video + optical audio = second best, S-video+ optical audio = third best

Don't worry about sending the TV audio to the Panasonic. Just send a digital audio signal from the cable box to the Panasonic.

DVD - Panasonic connected via HDMI
TV - Panasonic connected via HDI
cable connected to cable box and TV. But you will not really be using the cable connection to the TV (TV Tuner) since you will want HD feed from cable box through HDMI input on TV.

You aren't concerned about feeding the TV speakers because your audio will always come from the home theatre.

Note that some components don't feed audio through HDMI, in which case you will need to use optical digital audio.

I had the same problem
you have to set up the componant on DTV.
the signal my be hd 1080i and the only connection with componant that can support this is the DTV port.
the other componant connections only support 480,
good luck
