Smaller amounts of jitter can also be caused by HF noise on the input being used for triggering. Most good scopes have a low-pass noise-reduction filter you can enable for the trigger system to reduce/eliminate this.
It can also help to move the trigger level to a more stable point on the waveform, eg, near the zero-crossing where the rise time is fastest.
