Until last weekend i could play any AVI, WMV (not with DRM) or mpg files. Last weekend I installed two new application on my pc and since then I have problems of using media player. Sometimes a move doesn't work at all or other times I can watch the images but there is no sound.
I have read several article here and article 23781174 comes closest to my problem and as it is closed but doesn't really propose a solution i'm re-asking help on this.
The application i installed are Norton Antivirus, but no threat has been detected so far so i don't think this is the problem. The trouble probably started when i purchased and installed Pinnacle Studio 12 as it is codec related.
I have tried several codec packs mentioned in all the articles I found on this website but none solves the problem.
GSpot complaines it doesn't find a MPEG1 layer 2 audio codec. But again nothing I have downloaded and installed has solved the issue. I'm out of ideas. Can somebody help me solve this issue? It's not the first time I encounter such a problem although i'm not sure how it was solved last time but i think i plainly reinstalled the computer. This isn't an option for now on my current computer as I need it alot and don't have a day for the time I'd need to fully reinstall it.
