The code bellow executes well:

C:\mplayer\mencoder.exe -lavfopts i_certify_that_my_video_stream_does_not_use_b_frames " & C:\mplayer\Max.mpg & " -o " & C:\mplayer\Max.flv & " -of lavf -ovc lavc -oac lavc -lavcopts vcodec=flv:vbitrate=500:autoaspect:mbd=2:mv0:trell:v4mv:cbp:last_pred=3redia=2ia=2recmp=2:cmp=2:subcmp=2reme=2:turbo:acodec=mp3:abitrate=56 -srate 22050 -af lavcresample=22050


However the code bellow does not get executed:

C:\Documents and Settings\Eugene\Desktop\mplayer\mencoder.exe -lavfopts i_certify_that_my_video_stream_does_not_use_b_frames " & C:\Documents and Settings\Eugene\Desktop\mplayer\Max.mpg & " -o " & C:\Documents and Settings\Eugene\Desktop\mplayer\Max.flv & " -of lavf -ovc lavc -oac lavc -lavcopts vcodec=flv:vbitrate=500:autoaspect:mbd=2:mv0:trell:v4mv:cbp:last_pred=3redia=2ia=2recmp=2:cmp=2:subcmp=2reme=2:turbo:acodec=mp3:abitrate=56 -srate 22050 -af lavcresample=22050


I believe its because of the spacing or gap in the path such as

"Documents and Settings"


How is it solved?.
