Mbelia- I have had both in my house in the last few months. Sound from DSS is definately better, Pro logic or DD. My digital cable box from ATT did not have a digital out even though it was labelled DD. Even the prologic is better on the satellite. However, even using S-video out from DSS (not available on digital cable, a big disadvantage)both suffer from what I believe are digital artifacts in the picture on my 15 year old, top end (data grade tube) 27" Panasonic. However, viewing local channels is a real hassle with DSS, unless you are in one of the areas where they are available over the satellite. Lots of input switching on my DD rcvr using multiple remotes necessary, unless your TV can accept and easily switch between multiple video and audio inputs (unfortunately it seems that most sat boxes will only pass basic cable thru as an RF signal, so most HT/DD rcvrs cannot switch it). Sorry to be so long winded, but as you can see I am still trying to sort this out and am somewhat frustrated. However, if your viewing is mostly cable networks, premium channels, pay per view, or you want the special sports packages, you will be pleased with the s-video brightness, color fidelity, and the audio signal.
