Xvid+Ogg with GK

Hey guys,its been a while since i encoded something with GK,i have a question,i already ripped the ogg itself now i want to make a nice movie with Xvid+ogg,what should i choose in the Interleaving & AVI Overhead? No audio? 1x VBR? and should the Calculate Frame-Overhead be checked? i want it to add the audio by itself if possible. Thanx.

the calculation what I use in DVX is 0.04 % of the the overall size plus frame overhead which usually work good. len0x and and emp3r0r posted lately a little different formulas but since Matroska is near I'm too lazy for further researches on OGM. Note: If you use B-Frames with XviD you need to encode directly to OGM which cant't be done with GK

try "no audio" 

As Acalia suggested... and leave overhead checked...
