I was thinking about buying a player of this model: http://www.mustek.de/eng_/html/produkte/dvdpl408hm.htm

One thing I had in mind was to burn whole TV series on DVD-R with DiVX compression. In that way I'd be able to store a whole season on just two DVD-R. But now I heard from a friend that no portable DVD/DiVX player is able to play DiVX files off DVD-R(-RW/+R/+RW). Is that true?
