I have a dual boot system with Win98 and Win XP. In Win 98 videos play very smoothly. But when I boot into WinXP,there are problems with video animations,especially in full screen mode, they almost stop.
My system has 92 MB of RAM and just 450MB of free hard disk space on Win XP drive.
Does the deficiency of RAM and free hard disk space causing the animation problems
OR it is a driver compatibility problem.
It appears that you really didn't check to see if your computer met the minimum requirements for WinXP before installing the operating system.
I suggest that you browse the WinXP home page, and look for information regarding the minimum and recommended requirements, and check to see if your hardware and software is compatible with the new OS.
A "leap before you look" approach with WinXP can cause a myriad of different problems, as your questions posted in this forum are beginning to indicate.
While many of us here will be more than happy to help you troubleshoot an issue, or post additional, useful information, that is no substitute for taking the time to bring yourself up to speed. A great deal of information can be found on this forum with the "search boards" feature you'll see on the left column, and with the use of a search engine like <A HREF="http://www.google.com/advanced_search" target="_new">Google</A>, which is particularly good for locating specific information from the Microsoft Knowledge Database.
I also recommend listing as many specifications as possible about your system when hoping for a troubleshooting fix. This will allow one of us to make a better judgement call about the source of the problem, which will consequently be of more benefit to you.
