Virtualdub and TMPGenc?

[SlayerX]

I just added subtitles to a avi in Virtualdub with subtitler.vxt filter and then i started a Frameserver so that i can use TMPGenc to encode the avi to mpeg.
But when i want to open the frameserver in TMPGenc it says that it´s a "Illegal Stream Format"

Why?? I can´t understand what´s Illegal?

I never tried that, but have a look here (http://forum.doom9.org/showthread.php?s=&threadid=47483).
