I think you have hit the nail on the head. I moved avcodec.slb to c:\mint\1-18-cur and I was able to create an AC3 file.

Now the weird part. I have always had the slb files in c:\gemsys\slb but in the mint.cnf the path is setenv SLBPATH c:\mint\slb I wonder if I changed it to allow for the issue you mentioned ? Odd that it works now. It must still be ignoring the slbpath.if your 1-18-cur is current, then there is a regression some where, because vincent did fix this: 1) try current dir 2) try SLBPATH 3) try MiNT path
I'm not sure if I follow this. According to Peter SLBPATH is set to c:\mint\slb on his system. But he has kept the SLB's in c:\gemsys\slb. No wonder that MiNT didn't find them. So now that he moved them to $SYSDIR (but why not to c:\mint\slb?) they are loaded as expected.
Peter, have you tried to put the SLB's in the folder pointed to by SLBPATH? Jo Even
