I have what I know is a software issue with WMP 11 on WinXP. Watching videos
results in system freezes to the point of my computer crashing with an
infinate loop error. I have replaced the video card as well as uninstalling
and reinstalling the NVIDIA video drivers and it still happens. About a month
ago it began behaving after a system reboot and videos played again without
any problem but when I rebooted again a week later, the system came up with a
"recovery notification" message stating that it was reverting back to the
last known good checkpoint and the problems came back. No checkpoints I've
tried to use on the restore will fix this. There also was no new software
added before or after the brief period when the WMP worked properly. This
also effects other video players as well but not as severely as it effects
WMP (they hang but don't crash with an infinate loop error and system dump).

So, my question is this, is this codec related? If so, what so I do to fix
it (such as where do I get the codecs and where do I place them) ?
