I don't use the technique a whole lot, but when time stretching an audio file I always seem to get a noticeable number of 'pops' and unwanted artifacts. I am using the 'poly complex' algorithm in the MPEX3 setting, or the realtime setting.
Is there a better way (or better software) to minimise these unwanted effects?
Even on smaller 'stretches' it is noticeable and I do not have software like soundsoap to treat the file and I was hoping to avoid additional processing anyway.
Suggestions?

Melodyne is the best-sounding timestretch I've heard, but if you don't want to learn a new piece of software you can sometimes improve the sound of Cubase's (or any other sequencer's) on-board algorithms by stretching just a little bit multiple times, rather than a lot all at once. Also, if it's a rhythmic sound, you might possibly get a better result by chopping the audio up into slices like ReCycle does, placing the slices where they'd be at the new tempo, and right-clicking Advanced -> Close Gaps.
One important thing to remember when doing timestreching in Cubase (especially SX, not sure about Cubase 4), is that you should always do timestretching on a freshly-bounced audio file containing only the data you want to stretch (ie. select the event, right-click Audio -> Bounce Selection, click 'Replace'); if the event you're stretching is a segment from a longer audio file, sometimes audio from outside the segment you want to stretch can become included at the beginning or end of the stretched version, spoiling the sound.

timestretching is horrible... unless you use it as effect on something...
