how to play or convert .cpi extensions.

I have a sony vixia HD video camera. It shoots in the cpi format, which I cannot play once uploaded to my computer.  I have a windows 7 laptop, can someone recommend a free converter or free software that might play these files? Thanks

Actually .cpi  is not a audio or video files. The Orignal video file format is .MTS
and it is in the STREAM folder

I agree with using Media player classic to play the file but I would suggest downloading the full codec pack instead wich includes media player classic and all the relevant codecs you can get it at

Thank you very much, but what are cpi files? The audio from the footage is horrible, i'm wondering if it has anything to do with me taking the taking the cpi files.

(.CPI) Clip information file created by various high definition (HD) digital video camcorders; contains metadata describing an AVCHD video stream, such as the frame rate, frames per second, and aspect ratio; used to describe an .MTS video stream.

ok, the quality of the videos (mts files) are not HD quality. They're a bit pixelated and slow. Do you think that could be because I copied the CPI files from the camera then deleted them off the Camera, before I grabbed the MTS files? I still have both sets of files on my computer. Do you think I needed the CPI files on the camera when copying the MTS files?

pixelated and slow it is totally depends on the power of your system  

Media Player Classic - Home Cinema play .mts file perfectly for me.

Get Media Player Classic - Home Cinema from the below site download the 64bit or 32bit according to your os.

I use media player classic. And I have other mts video files from another camera, an HD panasonic. and they play with perfect HD quality and sound HD quality. However these mts files are pixelated and the audio is scratchy  and distorted. I'm still wondering whether that's because when I copied the mts files to my computer, the cpi files were missing, so could be missing some important sound and video data.
