Use the component. If your tv is running correctly it should not lose quality through the component system. HDMI is simply a High Def Multiple Interface, meaning that it combines the Visual with the Audio signal in the same cable. Refer to your documentation on your sattelite box to see if there is a solution. But remember that the HDMI may be carrying what the actual broadcast sound is as not many if any channels are transmitted in 5.1 dts.

Hello,
There are two things that I can suggest.
1-Test your optical cables to make sure they a good on a known working source because they are very fragile and break very easily.
2-Try to eliminate the use of optical output from tv to receiver. There may be a problem from the HDMI to optical conversion at the tv. Instead, try running the audio directly from the source to the receiver, and let the tv deal with video input only.
Hope this helps,
Good Luck.
