Alas, it's time for the pasture.
The build quality of the Sony S7000 is absolutely fabulous, and it would be a crying shame to turn it into a boat anchor. Sadly, the $89 Sony bottom of the line DVD player at your local department store has higher resolution video DACs, component video output, compatibility with DVD-R/+R/-RW, probably plays back MPEG/MP3/WMA Files, and probably works with the same remote control you've known and loved all these years.
Your Sony S7000 was the cream of the crop 7 years ago - I know because I wanted one so bad I could taste it, but couldn't find one for sale anywhere, and settled for a Pioneer Elite DVD-500 at the time. At $750, the Pioneer was an expensive player.... and I replaced it with a $129 Sony single-disc DVD about 2 years ago due to lightning striking the Pioneer. I'd never go back to the Pioneer even if it was repaired, the increased video quality on the cheap Sony was leagues ahead of the Pioneer -- not to mention the benefits of newer technology, component outputs, higher resolution DACs, etc.

Time for an upgrade!
