Poping sounds on some TV channels... (1 Viewer)

I'm using MP 2.2.0 SVN 1/02/07 Rev 12465. On some TV channels if I select it from the guide or by pressing channel up/down. When the picture initialy appears I hear several quick poping sounds then the audio is normal. It dosen't happen on all the channels, but the channels that it dose happen, it happens everytime. I have tried the MPA, Dscaler and Nvidia audio codecs and it still happens. Any ideas? THANX!
