Re: transcode-1.0.0-1.2.fc4.i386.rpm - segmentation fault

Posting for Jon...
Thanks for the update Jon, will give it a try.  Anyone else have any
suggestions?
==========================

For some reason I can't post directly to the Freshrmps list - this is what I
tried  to send though

I've been following your transcode woes with interest - I'll warn you
now that I don't know this kind of thing well enough to be conclusive.
Typically I try to rebuild the src.rpm so that I can include the divx
5.05 codec - with DVD::Rip.  I built the rpm but it fell foul of the mmx
bug for the rc1 source.
  I have however got a working transcode for the 1.0.0 src.rpm.  It
works OK with xvid and divx anyway.  Oddly though, the normal rpm was
found by DVD::Rip by my rebuilt version needs the NPTL workaround in
DVD::Rip to be located.
I've got an athlon 1900 + command line of DVD::Rip transcoding command
gives:

Ripping + preview grabs also work ok for me.  I'd test further if I knew
what I was doing.
