JVC XVN50BK Slim DVD Player
Heed Jeb6Kids advice!
I am experiencing the excact same 'stuttering' sproblem as Jeb6Kids below.  I do the excact same drill, and it comes back unless I turn the player off completely.  The picture (through component-to-HDTV) is quite nice, as is the sound, but this stuttering is intolerable.  I'm returning it tomorrow and might give the Panasonic 55 a try.
