Many many thanks for this bit of info. I have had a similar problem which has been driving me mad for a couple of weeks. Not only was I getting the noise 'white out' in certain parts of a couple of clips, but I was also getting occasional random green flashes in the picture stream (in different clips). These were not evident when played back in camera nor when played in VLC player but were always in the clips in Premiere (though not always in the same frames). I have just downloaded your fix as above and it has not only fixed the sound but also the green frames. I have run a split screen comparison in Premiere and the original still has the green flashes but the converted clip does not, and there is absolutely no difference in the picture quality, and as an added bonus I have been able to convert some .MOV files that I had been unable to play in Premiere.
The problem has only occurred in clips recorded at 720 50p.but not in all clips just the odd few. All footage at 1080x1440 or 1920 plays fine.

For info. Recorded on JVC HM700 to Verbatim 32GB class 6 SDHC cards at 720 50p (SD) (18.3 Mbps)
Dropped into PC Intel Dual Core 3Ghz with 4GB ram
Premiere CS4.

Again many thanks, TOP TIP.

I'm glad I wasn't the only one who had this issue on CS4. I recently upgraded to a HM100 to take storm and weather video. I took some test footage and took it home to play with on my system and liked it. Then when I brought it home, when I imported the footage the sound went from incredibly loud and disorted to virtually silent and fluctuated.

Well - I can vouch that the program suggested by Hans-Juergen definitely does work and solves this issue. But the other (rather odd) thing I've found, is if you leave the footage ON the SD card and edit from the card in Soundbooth/Premiere - then the audio is fine !! I simply thought it was my computer and it wasn't transferring the information properly - but obviously others have had issues too.
