Just a hint .....
If you already used TOK in the past... there should be a BBmpeg.ini file within the Folder where your encodings where finished.
Try to use this .... I got two of them in safe ... one from a 352x288 encoding and one from a 480x576 encoding.
... so if I join OneCD Encodings I always choose them in BBmpeg's "load settings" Tab .... therefore I never again had muxing problems. Cause IMHO of well presets within the BBmpg.ini files after the resolution specific encodings via TOK.
"Maybe" this could solve your problem. .........
"maybe"
Gimme via PN your email-adress and I'll send you the .ini this evening!
So you don't have to do a dummy encoding using TOK.... becuase TOK in installed state is deleivered with an .ini file for 352x288 only (as I remember), so don't choose the one within the TOK appl. Folder!
