The bad news in relation to EDTV vs HDTV is that you need a completely new TV or projector to display both EDTV and HDTV. Most DVD players on market today are progressive scan, meaning they output EDTV signals, however, in order to view progressive scan picture in all its glory, you need a TV or projector capable of displaying it and that, unfortunately, means getting a new TV.
In terms of content, there is very limited TV content available in HDTV format, and there is still wrangling about standard for HD DVDs. However, every DVD disc on market can be displayed in EDTV right now.
Bottom line? Pretty much every HDTV projector or TV on market today will display EDTV as well. So while there may not seem like a great deal of point in getting a new display for limited HDTV content that is available today, it is worth it to watch your DVD collection in EDTV, difference between SDTV and EDTV really is that big.
