I have been having problems lately when I rip certain disc. it began several moths ago with Unbroken and continued with Whiplash and most recently Terminator Genesis. I always rip the disc to the hard drive. However when I go to check the results using VLC the audio on the main track emits a series of blips and bleeps like it is only producing slight instances of the audio track. I also tried to rip it to an ISO and then copy it back to disc with ImgBurn or mount it with virtual clone drive but the same lack of accurate audio persist. Interesting enough if I convert the disc to mp4 or wmv the audio track is correct.
