Hi. I'm Steve. I'm sorry to hear about your TV. I will try my best to give you a precise and accurate answer.
You have just puchased a High Definition television. I assume that you did that so that you would have high definition pictures on the screen? You're not going to get that unless you use HDMI. SVideo is not capable of passing HD.
Bypass the 321 for video. Run an HDMI from the sat box to the TV. If the sat box does not have HDMI, it WILL have Component (red, blue, green). Run three RCA cables to the TV's own Component inputs.
Just ask if you need more help on this issue. I will be here.
Thanks very much.
Ok...Does the Bose have any type of HDMI input or output?
No. HDMI is digital and cannot be converted.
Again, you need to run video using HDMI from the sat box to the TV.
Run only audio from the sat box to the Bose.
Do not involve the Bose in any kind of video connection as you will not get high definition.
If you don't care about HD, simply run red, white and yellows from the sat box to the Bose and then to the TV. Frankly however, that would be like putting bicycle wheels on a new Lamborghini
Ahh...I'm with you.
Ok, Does the Bose have component outputs? This will be a trio of RCA jacks colored red, green and blue?
If they are all red white and yellow with a couple of SVideos then you would quite honestly be better off buying a more modern DVD player with component or HDMI jacks for $50.
Neither SVideo nor White Yellow Red jacks are going to give you a decent pic on that shiny new HDTV. You need Component (red, green blue) or HDMI.
You CAN run the audio from the new DVD player to your Bose so that you can enjoy the surround sound audio.
Sorry, I have been away today.
In reviewing our dialog, it seems that you are trying to take the DVD signal to the sat box and from there to the TV.
This will not work.
The TV has to have red, white and yellow RCA jacks for an AV input. The Bose has to have those outputs. Can't you simply connect the Bose to the TV with red, white and yellow RCA cables?
