Yesterday morning I installed the InterPlay software that comes with the "Band of Brothers" 6 DVD Box Set. Ever since, when playing(streaming) audio CDRs (mp3, WMA) off the DVD drive, I get a low frequency "popping" noise at random intervals (1 - 3 seconds) - very much like rain water dripping off leaves onto wet canvas - not quite as loud as the music. This happens only when playing a CD, when nothing is playing all is silent. Watching DVDs (Media Player or InterPlay) or playing music off the HDD are fine. I've uninstalled InterPlay but to no avail. Has a driver been tampered with that is used when streaming audio of a CD? Is the popping being produced when the mp3s or WMAs are being decided? Thanks, Matt.
