I hate to beat a dead horse but I do find it an interesting subject so I did some extra reading of that Dolby paper I posted a few comments above in hopes of trying to learn a bit more about EAC3 in general. This paper actually has a very interesting explanation for the EAC3 to AC3 transcoding process starting from page 22:

All Dolby Digital Plus decoders can decode Dolby Digital bitstreams." However, Dolby Digital Plus is a functional superset of Dolby Digital, and decoders include a mandatory component that directly converts (without decoding and re-encoding) the Dolby Digital Plus bitstream to a Dolby Digital bitstream (operating at 640 kbit/s) for carriage via legacy S/PDIF connections (including S/PDIF over HDMI) to external decoders (e.g. This is what it says on wikipedia: "Dolby Digital Plus bitstreams are not directly backward compatible with legacy Dolby Digital decoders. I didn't literally mean a lossless conversion but more like if you have a 640k AC3 track and a 1024k EAC3 track that gets converted down to AC3 because your receiver doesn't support EAC3, would those both end results sound identical or would the native AC3 track sound slightly better because the other one had to be converted from a "lossy" source. Or they simply refer to the Blu-ray profile, pushing all the features in marketing at the same time, eventhough you can't actually combine everything.
EAC3 supports higher bitrates then AC3, how could you make that a lossless conversion. That lossless conversion to AC3 is just theoretical marketing fluff. If a player cannot handle EAC3, it wont be able to play a pure EAC3 stream. Question - why on earth would you want to even bother with 7.1 AC3? Much better to use DTS-HD Master Audio. Scenarist is the best (indeed the only) player in town still actively developing and supporting their software. Sony bought up NetBlender, and promptly killed it off and it appears that their Blu-Print has gone the same way.

The only way to do it, is to use Dolby's Media Producer Suite.
