command line bug?

[mrconfig]

i have some trouble with the command line option. i started the bsplayer from a batch process with the following line

C:\Programme\BSPlayer\bplay.exe T:\DAS_GEISTERSCHLOSS_PART2.AVI -res=1280x1024x32 -stime=100 -fs -eend -as2

all works fine but then the i added -ar=4:3 and all other options had no effect, only the aspect ratio works fine.

C:\Programme\BSPlayer\bplay.exe T:\DAS_GEISTERSCHLOSS_PART2.AVI -res=1280x1024x32 -stime=100 -fs -eend -as2 -ar=4:3

is it a bug?

thx
