warning - nothing to output bframe decoder lag

[jgbfkh]

newbie here, please help one in need!

when i open my movie files they display this message on the thumbnail. the file is still there and plays normally after the message, but it is a pain in the neck not being able to see the thumbnails.

any ideas folks?

I've never heard of that message before. What format are the video files in?
