Thanks fore the response!
The sample is an .mp4 file.
Ripped it with Xilisoft DVD Ripper.
I'm using a MacBook Pro with a the Intel Core i7, 2.66 processor.
Final Cut Express 4.
And, yes, it sounds like the "bowels of Hell have opened and Satan has taken control of your computer." It's has varying speed audio of the clip with a lot of skipping, snapping, crackling, and, you guessed it, popping!
Like I said, the play back in the Viewer is fine, which leads me to believe the rip was fine. It's just after I render the clip that it gets weird. 😕
Thanks!
