AUI seems to be a hardware component, a plug (attached unit interface).
So, could you please tell us more ?
If it's an normal VideoVD, you should find a file named avseq01.dat in the MPEGAV folder. Open the file with BSPlayer and all should work ok.
If it's an SVCD then you need to install an MPEG2 codec
