Has it really been two years since Cleaner 5 was introduced? Cleaner 6 merges in MPEG Charger, is a little faster at MPEG encoding and preprocessing in general, and adds support for Kinoma (Peter Hoddie’s Palm OS media format).
There are caveats, though — it’s for Macintosh only, doesn’t support RealSystem or Windows Media 9 encoding on Mac OS X, and apparently takes a step backwards by moving codec-specific compression options out of the main Cleaner interface, which means that they can’t be scripted/automated. Hrmmm. Upgrades are $179 according to their press release, but $159 according to the Discreet site. Link Demo
