My workaround is to only delete when nothing else is recording. my best non-technical guess would be that drive intensive activity during recording will cause this.  I've always meant to try the "delete files slowly" option to see if that corrects it.

Yep, that would do it, assuming he's using the ext3 filesystem. That's
one big reason for the "slow deletes" option.
