Hmm, I can't. There's no crash here.
 Hmm, just realised I was using a copy/2nd instance of out_ds as out_ds2 (to make it use/load in_wm's built-in directsound output only as and when required, ie. for wma/wmv playback only).
I'll try to reproduce it again later, just using the 1 instance of out_ds... [/edit]
afaik, yes, you can delete unicows.dll, because it's now inside nscrt.dll
(nscrt.dll = msvcr71.dll & unicows.lib)
To be on the safe side, rename it to unicows.dll.off first.
If there's no problems after a few days, then you can safely delete it.
Important: Please disregard this.
unicows.dll is still required under Win9x/ME.
Further explained here.
