Hi Doug,
I'm not sure I fully understand the question.
I presume you are using the supplied software (Pixela??) to 'import' the AVCHD files from the SD card to your chosen directory on the PC.
Or you could (I think - unless others correct me for the Canon) just copy the files from the SD card to your PC using an appropriate card reader.
You should then be able to import the files into PD Media Library for use on the timeline.
Your message is normally shown when PD cannot play a file, often because the PC does not have the right codec. Is this what you mean?
I'm not sure about your file conversion to Windows standard comment?
Can you say exactly what you're doing and what file formats you are shooting with - FXP etc?
Cheers
Adrian
