EX1 CFHD/PHD 4/CS4: Corrupt Audio Import
 

I've seen at least two other users post this problem, but haven't seen any solution.
On importing HDLink converted (CFHD.avi) EX1 footage (mp4) into CS4/PHD4, the video imports fine, but the audio track is corrupt in an unusual manner. The first 1/4-1/2 sec of the clip audio track simply loops and plays over and over for the duration of the clip.
Non EX1 sourced clips (AVCHD, for example), converted to CFHD.avi, all import & preview normally. This problem only involves EX1 footage (1080 60i HQ) converted to avi with HDLink. Additionally, the original EX1 mp4 footage imports normally to a CS4 EX1/3 sequence.
The EX1 sourced CFHDs play normally in any other player, and have all been used in PHD3/CS3 projects previously without problem.
It's only a problem when importing into PHD4/CS4.
Any ideas??
