Aspect ratio converters?

There is many good points here. And there is a variety of alternatives available.

A graphics card with either s-video or composite output is good. I only mention the broadcast equipment because I recall buying the stuff new 20 years ago for tens of thousands of dollars and now exactly the same stuff is worth a hundred bucks.

Personally I prefer center cut 16:9 on 4:3 even though the captioning may be cut off. Then again I prefer older programming on older sets. There were many older movies, television programs and series I never had time to watch in the 60's and 70's I can watch on line or off DVD. And all of it was 4:3 or close enough.
