Thanks guys, have #'d out the CRON file I wrote to :

00 06 * * * (touch /var/timestamp; /hack/bin/force_index.tcl) &

Shouldn't be required and was at best a work around to bandaid the problem but sometimes messed up the TiVo suggestions for a day.

Appreciate the help, the 1.4 image I used was quite early and obviously has some issues...
