Problem with autorun.inf

[SupremeDementia]

okay here's the idea : autoruning a VCD. So far so good, but this VCD has 6 .dat files

unfortunately this didn't work:
[autorun]
open=start mplayer2.exe /play /close \MPEGAV\avseq01.dat
open=start mplayer2.exe /play /close \MPEGAV\avseq02.dat
...
open=start mplayer2.exe /play /close \MPEGAV\avseq06.dat

any ideas on how to fix the autorun without messing with the dat files ?
