Problems
I can't install Vobsub. Vobsub wont work.
Try use latest VSFilter instead. Install it and then copy the VSFilter.dll to the plugins folder under the Virtualdubmod folder and rename it to VSFilter.vdf. Like c:\program files\virtualdubmod\plugins\VSFilter.vdf

VBR audio stream detected
Just select NO.

Can't see any DivX or XviD in the compression list
Install the DivX Codec or Xvid Codec.

Can't open the video
Identify the video codec with Gspot or avicodec. Then download and install that codec, usually DivX Codec or XviD Codec or try ffdshow(and enable VFW decoding)

The source image format is not acceptable (error code -2). Or other problems.
