If you crash, do you get a core dump?  If not, could you bump up your 
dump limits so you do get a core file?  A backtrace from that, and 
possibly your logs, would go a long way to diagnosing an issue.

The MythVideo scanner in MythWeb is somewhat broken.  In 0.22, it was 
not capable of scanning storage groups.  In 0.23, it will only scan 
storage groups, but it only scans on the local machine, and it doesn't 
use the new hash value which can cause problems elsewhere.

JAMU includes a scan that also only scans the local machine, but it 
inserts proper video entries.  The python bindings will perform a full 
remote scan, as detailed with this script 
(http://mythtv.org/wiki/Myth_video_scan.py) which does that along with a 
crude metadata lookup.
