You need to contact DirecTV to correct this problem. It may be something that they are doing with the program settings on the DirecTV computers for your receivers that is causing this problem. Good Luck.   « less

Well if there is nothing wrong with your set and you made sure the connections were good. Then I believe that your cable boxes have problems. Have Comcast replace your boxes for you.   « less

Well Nate, That is a very good question. The programming is the same as analog. But the picture is much better when there are HD programs on, which is not all the time. The channels are no longer just 2,4,5,7, etc. They are now 2-1,2-2,4-1,4-2, etc. Note the dash in the channel. Also note that there are multiple channels for each station. There is different programming on the different channels for some of the stations. Also the digital stations do not just appear on the set the first time you connect your antenna to it. They must be searched for with a scan to capture them to watch. After the initial scan the set will know about them and you will just have to change the channel. In most locations in the San Jose, California area a TV will pick up about 30 different channels with a good rooftop antenna. And they are all free for the watching.   « less

Hello Gymbo, If you aren't getting ABC from Dishnetwork and you don't have cable in your area or can't receive it by a rooftop antenna. Then you are going to have to convert to DirecTV. That is the only option that you have.   « less

Hello Joey, If the HD PVR you have has an S video output then you will have to connect them with that. If the television is not an HD capable set than you aren't going to see an HD quality picture. All HD capable sets have either one of the following inputs, component, DVI or HDMI.   « less

Hi Anthony, Yes, your in luck there are cables that adapt DVI to HDMI. You can buy them at most major Home Electronics retailers or on the internet. But when you use these cables you lose the audio connection through the HDMI cabling. So you will have to make the audio connection between the DVR and the television with the proper seperate cabling.   « less

Hello Andrea, That is a very good question! A lot of people are confused by this very same thing. The HDTV tuner on the TV will only give you an HDTV (ATSC) signal through an antenna input from your local broadcasters over the air. It will not give you an HDTV signal from the cable company unless you use their digital cable box and are paying for the upgraded HDTV signal package. They will still not pass you that signal through the coax cable. It has to come out of the HD digital box through either the component connectors or the DVI connector. You have to pay extra for the HDTV programming from the cable company as well as through a satellite TV provider. I hope this clears things up for you.   « less

It sounds like you have your audio cables on the wrong input from your video cable. If you don't have your audio and video cables on the same input of your receiver than you will hear the audio but not see the video. This is a common mistake with so many different inputs on a receiver these days. Double check that they are on the same input. I am sure that that will fix your problem. Have a happy A/V Day!   « less

Hello Wayne, That is a very good question. And a very hard one to answer easily. That is like asking me what is the best TV to buy. It really depends on what is important to you as far as what you mostly watch on your television. If you are a big sports fan than I suggest that you go with DirecTV. Because they offer the most sports packages. If you want to watch mostly HDTV programing then Dishnetwork offers the most HDTV channels 20 right now. But DirecTV will be coming out with over 100 HDTV channels this next year 2007. That will put them on top for HDTV in the near future. To get the most local HDTV programming you will need to have a rooftop antenna. Neither cable or satellite transmits all of the local digital channels because they don't have the bandwidth for it. As far as picture quality both satellite companies offer the same quality. Cable has the worst picture quality from what I have seen. I am an authorized DirecTV dealer if you decide to go with DirecTV.   « less

Hello Keith, It doesn't really matter which type of cable you run for the audio unless you are trying to achieve surround sound through a decoder. Then you need to run either the coax or optical cable. The coax would be the cheapest cable to run at 25 feet. The optical would give you the best audio quality at that length. The easiest is to run the HDMI cable. Then you only have to run one cable for both audio and video for good quality for both. But this cable will run you about $100.   « less
