Best option would be an HTPC. There's too many ways you can encode movies in divx/xvid, you can't expect a divx capable dvd player to always play a file correctly.
New dvd players featuring the latest sigma designs chip should be good like the avel linkplayer2, buffalo linktheater, and snazio player. These are capable of playing divx hd/wmv hd. The Oppo player can play divx/xvid also but not hd files and uses the mediatek chip.
