DVDs cause audio problems

Hi. Hope I’m posting in the right place. I have a question regarding DVD audio problem.

Every once in a while an original DVD that we rent and play on our PC opens up with some kind of advertisment for Interplay … or something like that, if you click on it by mistake you loose your audio and Power DVD displays “update audio” in the set up window. The only way I found to solve the audio loss is to reinstall the DVD and let that screen show up again, then click cancel on the screen. When I do that eveything comes back.

Has anyone any knowledge of something like this?
