In his interview at Bristol for CineNow Bob suggested they were only using one of the available filters, presumably those on the 7200 and not 808.2, in their 7200/808.2 system. Or did I misunderstand?
Unless I've misunderstood (which is completely possible

), the apodizing properties of the filter are tied up with the upsampling. Presumably then, if you've already upsampled (808.2), you won't re-apodize. So I assume it was the 7200 apodizing filters that were redundant.
This is, of course, the reason why we need(!) the apodizing upsampling in our processors: To handle all non-apodized two and multi-channel source material. Otherwise, all other processor work, such as DSP, time-alignment and room correction will be done at low res.
