VLC: Using new codecs

G'day,

I've tried Portable VLC at a couple of locations. At home, I have k-lite codec pack installed in windows with ffdshow etc to play back AVC codecs like x264. On my work computer though, P-VLC just shows a blank window where the video should be.

Does VLC need any of the windows codecs to be installed - it shouldn't to be portable! Should I copy the AVC codec DLL file into a directory on my flash drive?

My video is compressed as x264 with AAC audio in an MP4 container.

Cheers
