[CentOS] mpeg4ip (from Dag) vs CentOS 4.4 64-bit?

Anyone else on the list using these tools?

I grabbed the latest iteration using yum from Dag's repository, but I 
get random segfaults on a fully-patched 4.4 system on dual Opteron 275's 
from some of the utilities.  Perhaps, it's some 64-bit vs 32-bit-ism?  
I'm not much of a programmer (actually, I'm a terrible programmer) so 
any suggestions would be very much appreciated.  :)  The machine has 
otherwise been bulletproof so I'm reasonably sure it's something fishy 
with mpeg4ip.

Cheers,
