I have recently encountered a strange problem. Whenever I browse movies of AVI format in Windows Explorer, it hangs up Windows Explorer. I faced the same problem earlier also. Whatever research I did on the same earlier it was mentioned that it has got to do with some codecs installed. What is the problem and how can it be solved? I have lot of movies in AVI format and I seem to have trouble everytime I browse through them in Windows Explorer. Please help! If this was posted earlier in any of the threads I apologize!
