Codec Problem???

Question

Ok, seriously you'll need to read the ENTIRE question to answer accuratly.

Now my brothers computer system has always been able to play DVDs though windows media player. Today his system for some reason refused to play DVD SOUND (only, video ok) though his computer. Now it has always been fine before. I opened the system up, found nothing loose, reconnected all cables (including sound from CD drive to motherboard)...did not fix problem...after about an hour of tring to understand the problem, I put in an audio cd and it worked, but still DVD sound did not. I ended up installing a third party DVD playing program that came with codecs, and now (in the new program, not windows media) he can see video and play sound from a DVD.

My question is, what do you think actually caused this? He has done nothing that changed system settings today, did not install software, change reg settings, virus/spy scan turned up neg. What do you think caused this???

windows has always been an unstable program. a simple reboot may solve the problem. he may need to reload windows media player. it happens. its just windows being windows.
