AVCHD and Mac seems exist a long breaking-in period, until the half second year of 2011, we till see the problem from discussions apple:

"I've imported some video from a Sony HDR-CX305E camcorder, which shows up as AVCHD in the import window, and selected the FULL file size. Everything goes fine and the video looks fantastic on my Macbook.
When I export the finished, edited movie to iDVD, regardless of the resolution I select, the finished DVD when played through my PS3 is of horrific quality.

I am wanting to know if I am doing something wrong here - why can't I get a better resolution from the finished DVD? I thought that AVCHD meant HD quality on a DVD as long as it was played in a Blu-Ray player?"

We've waited for a long time and it's glad to know iMovie is able to accept rather AVCHD Camcorders from Sony, Canon, JVC and Panasonic. Though still most other AVCHD models have importing problem with iMovie, but the above question is iMovie export bad quality MOV or DV format so after editing on DVD, it also export poor DVD quality.
