How to import Quality Videos on Sony Bloggie?

I have a HD Bloggie PM5 model. The issue is when i import the videos to my computer they look like crap. When i play them on the actual camera they look flawless. The issue is when i import them. I tried copying the video direct from the SD card but it just makes it Play(skips frames, freezes, etc) worse than using the built in importer. Any help?
