Kent, you have to copy the whole AVCHD to your hard drive and once in premiere it should show up. Also, what are the settings on the camera, for example, are you shooting 1080p, 720p, or 480? When you render with H.264 in the field order use none and use the bit rate at VBR, 2 pass and move the slider to the right. If using Quicktime, use video codec, None and always click the render at maximum depth. Let me know if this helps or if you have any other questions.
