Yamaha DVD5750 Progressive Scan DVD Player
You can't go wrong with the Yamaha DV-S5750
There aren't a lot of reviews out there for this player so I thought I would write one based on the my experience during the last couple of months.  First of all there is nothing that hasn't played on this unit since I bought it and that includes multiple DivX formats, DVD's that my old player wouldn't play, etc.  It also appears that the picture quality is actually improved making lower quality video like DivX look better than it is. I have not experienced syncing problems with audio or glitches in the video.  All controls are easily adjusted via on-screen menus and therefore the face of the unit remains clean and basic.  The sound quality of CD's is incredible using quality components to accompany it.  I use a digital connection and have yet to try the upsampling function for analog sources.  The bottom line is although you can buy cheaper DVD players that provide the same functions as this unit, in my research, you can'not get a better buy on a quality unit with solid components that are assured to last, and provide quality video and sound.  Very pleased.
