I also found the solution in Doug’s post but after applying fix found MPEG2 presets disabled (there may have been others disabled as well but I was mostly paying attention to the missing MPEG2). I was able to enable ALL export formats (Quicktime, MPEG2, FLV, etc) by:
• Keeping the original AddExporterList.txt in “Adobe Media Encoder CS6/Contents/Resources/txt/”
• Changing the extension for each of the actual bundles that AddExporterList.txt is importing from
“Adobe Media Encoder CS6/Contents/Plug-ins/Common/Exporter[FORMAT].bundle”
to “Adobe Media Encoder CS6/Contents/Plug-ins/Common/Exporter[FORMAT].bak.bundle”
That way AMC will still keep the default presets but will fail to load the bundles for the additional formats once they’re imported. Obviously the use of “.bak” is a bit arbitrary. Too early to tell if there’s any drawbacks for this method, but I’d tend to think there wouldn’t be.
