I have some problem with my HTPC. When I look at a avi movie the picture sometimes hangs but the sounds goes on. The only thing I can do then is to stop the movie and then start it up again. I have a AMD Duron 800MHz, 128MB RAM and a GeForce2 MX 200. I have used Media Player, Zoomplayer and Power DVD but it is the same with all of them. I have installed the latest codecs by installing Nimo Codec Pack (http://www.nivelvirtual.net/nimo/). Has anyone experienced this and, if so, how have you solved the problem?
