By chance, are you initting the QCRenderer on one thread and using it on another? If so, you *cannot* do that, and you will leak textures.
Ive used the standard and the v002 Movie Player in various compositions and apps and have not seen leaks. You also should test the leaks over a longer period of time. QC's cache will retain images pat the current frame, in case it needs to be re-used. Ive noticed in small apps what looks like leak (memory usage climbing after the comp is loaded), but you will (hopefully) see that taper off and reach a local maximum for the loaded comp, and float around a memory value. The Leaks tool picks those up as leaks, but in reality its handled as a cache. Are you seeing continuous memory leaks over long periods of time, (like more than 20 min?), and not a continuous rise in memory usage after a minute or two, then a tapering off once the caching has determined the optimal memory size ? How much memory is leaking per frame?
