You can indeed. The setting is PreviewPixmapOffset if you want to edit
it via MythWeb(value is in seconds) but it's also exposed in the
settings somewhere as well.

I have a 5 minute pre-roll and tell MythTV to take snapshots 9 minutes
in. I have to admit the snapshotting doesn't always create a pleasing
result though(ie. one recording of Ideal has a snapshot of a semi-naked
Johnny Vegas), but that's hardly Myth's fault.
