Do you have any pre-roll with negative frames ? That sometime can cause similar problem. Starting pre-roll on the positive side might help.

I'll give this hoop-jumping a try, thanks for the voodoo :-)
However, this is the key motivation for my plea to Softimage. They should not spend any time on logic trying to figure out if a sim is clean or dirty, since any errors or loopholes ultimately lead to huge amounts of frustration in the user base.
Instead, just provide a switch... write cache or read cache.
It's simple, and any mistakes or accidental overwrites are my fault, not Softimage's.
