How does this thing work?

[crazypotato]

I got DD 1.4h. I can't get the video to display probably no matter how hard I try. It is going out of Sync and jerky. I can hear audio ok. Screen is horribly problematic. Did I miss something here?

I had no problem before with the very old DD. Can someone shed some lights on how to make this thing to work?

do a clean installation to another folder.
use Intervideo codecs (best for compatilibility and stability)
Get these codecs from the latest WinDVD trial version.
