So I just got a new computer and re-installed my preferred version of EAC3to.
When I try to slow down something PAL, this is the error I get:

"The Nero decoder doesn't seem to work, will use libav instead.
Removing dialog normalization...
Reversing PAL speedup...
Loading white noise (needed for dithering)...
Failed to copy and load the r8brain dll.
Aborted at file position 16384."

Any suggestions as to what's happening? I've re-installed it with the same results, unfortunately.
