[PROBLEM] USB 2.0 DVDRW can't read DVD

[rikardo1979]

i dont want be so pessimistic but I dont see the way with the RPi CPU and amount of RAM.
The thing that RPi is capable to play Full HD is that all is go through GPU whis is fully used by omxplayer.
Also thats the way why none of the external players would work as there would not be HW acceleration.
So to me this is a dead end an I would just recommend rip all your dvd or iso to something like avi or mkv
