Mpeg->wmv troubleshooting

I have a vob file that i have renamed to *.mpg. It runs just fine.

I want to encode it to wmv. When I try to use Windows Media 10 or Encoder 9 the encoding takes place and seems to be ok, until about 80 percent through the file the file simply “ends”. No errors…it just doesn’t have the end of the file.

I have found that AVS video converter works fine…it does the conversion w/o a problem.

Is there a setting I’m missing so that this will work directly with the Windows encoder or Windows Media Player without ending before the file is over?
