I just bought a new player for my wife for Christmas. It is a Philips 851/37, a portable DVD player which has an 8.5" screen. It also plays:
CDG
VCD
CDs (and DVDs) with MP3 files
CDs (and DVDs) with JPEG files
It has a SD memory card slot as well, which I haven't tried. It does
not recognize MP3+G -- I tried.
She will use it for carrying tunes to voice lessons, so she can see the words to songs she is practicing. She will undoubtedly also use it for showing pictures. Maybe even for watching movies.
I hope to also use it as a show player for CDGs -- if that works I will look for another. People who bring in CDGs will be able to see the words on it, without having to add video capture for Compuhost.
