Quoted from WARHURYEAH

Trying to use the new PLDX encoding tool, when I select the video I want to encode, I select the h264. option etc. Hit encode, a black box comes up for a second and it says it’s finished without anything being completed or the finished file being there :/

And with the old version I get Mencoder has stopped working and it crashes :/ what is the problem?

got the same problem when trying to encode a lagarith avi. Uncompressed worked for me.
