The Xenta DV 1013 is one of the smallest front loading DVD players I have come across, the picture and sound are both good and you can connect up a surround sound system although I have not tried that.
It plays both WMA and MP3 audio as well CD's of course, JPEG picture discs and XVID.avi video but not despite what it says in the manual DIVX (.divx) or MPEG 4 (.mp4).
The main limitation I think is lack of connectivity, at the back all there is a SCART and a coax for digital audio.
But if your looking for a small inexpensive DVD player that perhaps does more than it looks I can recommend it.
