Ok I think I fixed it. I had to rename the raw files to a .zip. Just change it to MTS. Otherwise it seems like the browser tries to open the raw data in the browser window...
Also noticing some buggy behavior with those mp4 files and I saw this post:

I am having similar trouble (I have 32 bit WinXP pro with 2GB RAM and nothing running in the background).
thanks,
