I know this is probably a dumb question, but why isn't there an easy way to losslessly convert 24p in a 60i stream to regular AVCHD 24p, and STILL have it be AVCHD--I mean, shouldn't it be possible to just ditch the extra frames, and have a slightly smaller file that would mirror exactly what is recorded on a Canon cam that has "real" 24p?

Dumb AVCHD question, in search of 24p AVCHD

It's because AVCHD is a heavily compressed ACQUISITION codec -- it is used to capture and there isn't a single program for either Windows or Mac (that I know of) which can output or render to AVCHD.
You're asking the program to take the 60i AVCHD stream and output it to a 24p AVCHD stream...there's no such program (again, that I know of) since AVCHD is used for acquisition only.

The frames in an AVCHD file are dependent on each other and so it is near impossible to remove one frame and leave the other. If you plan to edit the file, it is better to convert it to DNxHD, Cineform, ProRes or similar before editing. While converting you can easily throw away the extra frames and obtain true 24p.

AVCHD is so similar to blu-ray that most H264 blu-ray encoders can be used to create AVCHD files.
