When i convert an SMR video to mpeg it gets purple blocks all the time! Might happen with Divx too but i have only downloaded SMR movies since i rebooted my computer. I also really have to convert the files cause i'm having a hard time playing SMR videos in full screen. YOu know when you first watch something in full screen it lags and looks bad then it blurs over and runs fine, well it wont blur over and start playing normally.
