Dud rows of pixels with ffmpeg-static

[Neill Mitchell]

Hi.

Thanks for digging around. That would certainly explain it. I remember 
seeing the brainfart messages last time, but I'm not seeing them this time.

I tried the static ffmpeg again, but saw the dud pixels again. Very odd.

I've just upgraded Ubuntu and it now has ffmpeg 0.7.2, so I'll try that. 
Failing that, I'll build the very latest from source. I'll let you know 
how I get on!

Thanks for your help with this :)
