Actually the problem occurs when I don't use -of mpeg.  I only tried '-of mpeg' to see
if I could solve the problem myself.  In fact, with '-of mpeg' mencoder hangs and never
produces an outout file.  So, the slow seek forwards occur with the AVI format.  And,
I also have other vidoe files with the same encoding parameters that don't have this problem.
The only difference is those files were encoded straight from the raw captured video, while
the problem files were first inverse telecined.  So could the inverse telecining be causing this
problem maybe?
