Agreed, just keep in mind that the current stable AviSynth v2.60 contains a somewhat outdated version of TimeStretch which cannot handle 6-ch sources.

If you want a newer TimeStretch version which is not restricted to stereo you can either download Wilbert's TimeStretch plugin

or use the latest AviSynth v2.61 Alpha version which features an even newer version...
