.MOV to FLV not happening

[makman]

Ok, so I'm dropping my .MOV (Sor3) file into the correct field, making sure the setting in the FLV field are correct and the file is the same size and frame rate as the QuickTime but when I press encode I end up with a file of zero kb. What am I doing wrong?

This might help:

Though I'd found the problem as 3 plugins/codecs? hadn't been loaded. But no, now I get:

I have found a simpler workaround, which is that you encode from .mov to .mp4 using x264 (mencoder) at the same size and bit rate, then go to flv from there. This has worked great for me with DVD-sourced video at high bitrates, but I haven't tried it with source material at lower bitrates.
