OK, I think I see the problem; the German text is kind of misleading. It mixes discussion of the R600 (which does not have UVD) with the rest of the HD2xx family (which does have UVD). The first time I read it I also thought it was saying that Avivo HD acceleration was done on the stream processors, but what it's *trying* to say is that decode acceleration is done on the stream processors for HD2900 but is done in UVD for the rest of the HD2xxx family.
The UVD parts do make heavy use of the shaders during video playback (and we are able to keep power consumption very low), but the work done on the shaders is mostly post-decode processing; filtering, colour space conversion, de-interlacing etc...
