Mountain Lion won't display .MTS files from camera SD card in the finder

Question

OS Mountain Lion will not show .MTS files from my camera SD card in the finder.
I don't want to play them. I just need to see a list of the files so that I can copy them off the card onto a hard drive. I know how to convert them.
I have a Panasonic High Def video camera that records .MTS files.
I understand how to convert MTS files for editing in Final Cut Pro. It is not a problem. I have  been doing this with no problems using OS 10.7.5
I plug in my camera, and the SD card shows up as a hard drive in my finder. I click on the hard drive icon and it opens several folders. DCIM, MISC, PRIVATE.
I click on the PRIVATE folder and subfolders open. I click on the AVCHD folder, and then go down to STREAMING, and there are the MTS files.  I select them and import them into BIGASOFT video converter and convert them to .MOV files, which I can edit in FCP.
So that works great in OS 10.7.5
Here is my problem:
On my new MacBook Pro with OS10.8.3 I plug in the camera. It reads the SD card.
I see the folder DCIM and I see the folder MISC. But the PRIVATE folder (where the .MTS files reside) shows up as a QuickTime icon.  I click on that, but the MTS files do not show up.
I don’t need to play the MTS files. I don’t need to know how to convert them. I can do that.
I right clicked on the PRIVATE (not folder but QT icon) and selected "show package contents." That gave me another list, with an icon for AVCHD, but when I right clicked again and selected "show package contents" the MTS files would not appear.
I just need to be able to see as a list and copy them on to a hard drive.  Why does Apple make this so hard? 

Answer 1

STEP BY STEP INSTRUCTIONS TO RECOGNIZE AND IMPORT MTS FILES. (No help from Apple.)
After 4 frustrating hours and about 40 useless minutes wasted on Apple Support chat, I figured this out.
Okay, here are the steps to allow Mountain Lion to see your MTS files on a Panasonic camera SD card and import them:
Click on your camera SD card.
RIGHT Click on PRIVATE icon. (This used to be a folder, now it is a Quicktime logo.)
Pull down command for “Show Package Contents”
Click on AVCHD
Pull down command for “Show Package Contents”
Click on BDMV
Pull down command for “Show Package Contents”
Open the folder called STREAM
There are your MTS files. Select them and copy them to a folder on your hard drive.
Purchase some type of video converter (I paid 30 bucks for Bigasoft Converter and it works.)
Import the MTS files into the video converter and set the commands (This is several more steps, which you will have to figure out.) This will take quite a while for large, High Def files.
Save converted files to your hard drive.
NOW, finally FCP X will let you import and edit your files.
Thanks Apple for adding 12 steps where it should take one. “Log and Transfer” or IMPORT.  You should fix this.
It took me about 4 hours of frustration to figure this out. Apple support chat service was no help at all. The girl in chat had no understanding of video files.
Thank you Apple, for hiding these files behind your Quicktime logo, thanks for adding extra steps and decreasing productivity. I've been using Macintosh computers since 1987. I would not own a PC, but Apple is not what it used to be. Why would you not just let the .MTS files show without hiding them?
