PSP Preset not working

After transcoding a set of videos to the PSP format, I transfer them to the PSP and it simply says "Corrupted Data".

Thanks.

Start by reproducing the PSP preset failure with a representative video and inspect the generated files against the PSP's accepted format. The issue mentions no source files or tests, so locate the preset implementation and any transcoding tests first. Done means a transcoded video transfers to the PSP and is recognized without a “Corrupted Data” message.
