I get this message 'Unsupported format/damaged file. One of the necessary components may not be installed.'

I use an Hitachi HDD video camera. It came with image mixer 3 software that I use to import the video onto my PC. It saves the files as mpeg 2 and then in PE4 I can import the media into my project to make videos with.

This has always worked and I just made 6 small videos the other day in this manner. Now I just tried doing this today and I get that error message and the mpegs are unrecognized by PE4. I tried it with the mpegs that I used just 3 days ago and I have the same problem.

I have uninstalled and then reinstalled PE4, I used gspot to make sure I have the proper codecs for the mpegs, quicktime is up to date. I'm not sure what else to try.

Anyone have any ideas? I have some clips that I need to get made.

Thanks
