i've captured a file in iMovie 3 and i use ffmpegx to encode it to MPEG-2, by loading the 3k Quicktime reference movie into ffmpegx. it's worked fine on the last version I tried (0.0.6g) but when i downloaded 0.0.6m last night, and installed it (terminal said that the installation was successful), i get this error message:

can't open '/Users/mark/.mplayer/codecs.conf': No such file or directory
can't open '/usr/local/etc/mplayer/codecs.conf': No such file or directory
File not found: 'frameno.avi'

============ Sorry, this file format is not recognized/supported =============

any idea what the problem is?
