as far as your VBR is concerned, i agree with lattesurf. converting them to a stable bit rate using a free program like Audacity would solve problems like fast/slow running of songs, static etc.
Audacity
as far as your videos giving Format Errors are concerned, i agree with the admin. while converting your videos using amv converter, try using medium image quality. not only do they remove format errors but they also reduce the output amv file size reasonably without any visible change in my opinion.
if the problem persists, i would like you to follow this :
