Audiovox D1420 4.2-Inch Portable DVD Player with Built In Rechargeable Battery
Does More Than I Expected
When I bought this I was hoping it would play mp3 from DVDs, though it only advertises mp3 CD.  It does, handling the DVD just as it would a CD (full directory access and automatic progression between songs).  Now I can carry all the music I want during a trip on a single disk.  It also plays DVD video just fine from either burned DVD-R or DVD+R disks.  The picture is good for such a small screen.  The only odd thing is that it is not set for optimum viewing straight-on.  The unit needs to be tilted slightly downward.  Presumably that's to allow for it sitting on a surface below eye-level.  A (minor) quibble is that it is a bit thicker than the photo would suggest.  The battery pack is mounted external to the shell within the rubber casing that surrounds the player.  It bulges from the back of the unit.  Overall the unit is still fairly compact, but a bit big for a briefcase.  To me, the flexibility of media options outways the slight extra bulk.
