0kb FLV conversion problem

[exitmusic47]

This seems to be a common problem from previous topics but I'm starting a new topic about it anyway seeing as, from what I've observed on this forum, it still has yet to be solved. I need to convert an mov file to flv. It takes less than a second to "encode" and results in a 0kb file that doesn't do anything. Setting the scale from fast bilinear to bilinear is not an option for when encoding to flash. I've checked "invert mapping" for the audio. I've made sure that the size is set to 320x240. The name of my hard drive does not have any spaces or unusual characters. These have all been suggestions on previous threads but none of this helps. Has anyone found a solution to this problem?

Here's my log if it helps:

At the worst, try encoding first to iPod h264 and then back to FLV.

It actually worked! Thanks!
