Philips DVP642 Xvid playback capabilities

I read some of the threads regarding Xvid playback and saw that some people mentioned xvid 1.0.2 videos not playing correctly? How does the divx/xvid decoding quality compare to the OPPO OPDV971H divx/xvid player? Just to make sure,the DVP642 has to ability to play DVD-R discs in addition to DVD+R, right? Thanks!

The DVP642 plays -R disks with no problem. As for your other questions, I have no idea, sorry.
