Did you try using the AVCCAM Viewer software from Panasonic? It enables the Mac to directly view native MTS-files via a QuickTime plugin, eliminating the need for recoding.
Download it directly from the Panasonic website: https://eww.pass.panasonic.co.jp/pro-av/support/desk/e/download.htm
Maybe this helps...
Red the article.
As i said the files are on my HDD not on sdcards or the cam anymore. So the article couldnt help me.
I tried to put them back on the camera but they won't get imported. I suppose it's because once you delete them from them cam you cant put them back correcty because some thumbnails or metadate is missing. At least i havent figured out a way jet.
I little bit more backgound on this issue:
I was on holidays with my cam and no mac. I shoot 80gig of film during that trip and used a friends netbook to back them up.
Once home again i put that videos on my mac and tried to import them. That's where i got stuck.
I have same problem you have described. Importing works perfectly from my camera but previously imported MTS I get the same problems as described in the support forum. http://support.apple.com/kb/HT5251
Any other ideas?
The solution that works for me for .mts files that are not on the camera. This works when the files are on the hard drive and you are trying to import them to iPhoto or iMovie.
I use a free app called Media Converter http://media-converter.sourceforge.net to RE-WRAP the file into .mov extension. This is done within seconds and this does not convert or compress the .mts file. It rewraps it into .mov so the iPhoto and iMovies can import it. And you can also play the file on Quicktime.
Remember after downloading the Media Converter to also download the correct preset from the "Presets" tab on the website. The right one is "Re-wrap AVCHD for Quicktime - uncompressed Audio".
This has been working for me fine, with one drawback. Once you rewrap the file, it loses the correct date and time the video was taken. So I have to fix the date and time of the file in iPhoto.
To help with the file dates, I found an AppleScript that will copy the file date stamps from one file to another file. After using Media Converter, you should have new file(s) with the same name as the original mts file but with a different extension (e.g. - original file is "Movie1.mts", re-wrapped file is "Movie1.mov"). Using the script below, it will take the file-date from "Movie1.mts" and copy it to "Movie1.mov". Note: Put all files in the same directory.
You'll need to customize the script by changing a few lines:
- MacHD:Users:Shared:MovieFolder-->change to the path where files are located on your Mac.
- name extension is "avi" or name extension is "mkv" or name extension is "MTS" --> case sensitive, these should be file extensions of the original files you want to copy file-date FROM.
- "mov'"--> this should be the file extension of the new files whose file-date you want to change
- The 'label index' settings are just color coding of files to help identify processing status, you can remove those if you want. FYI - To change color coding on files you just right-click file and pick one of the colors under "Labels"

From messing with .MTS on my Panasonic camera a while ago...
Drag the .MTS files onto your desktop. Using the Finder, select the file then choose "Show package contents" you should find the .MTS is just a container for another video format, possibly MP4 or MOV which can be dragged out onto the desktop; this should play OK in mts to avi for open it.
