I just downloaded and installed the VLC player.
Started the avi file and it played for approximately 2 minutes. The
screen
resolution then changed - it appeared to elongate vertically. About 2
minutes later, the screen went to a white background with vertical, jagged
blue lines. The audio continued as described in earlier posts. I could
not
find a work-around so I had to turn off the computer.

Please clarify, have any of these problematic video files + DVD's
previously played OK in both WMP and PowerDVD on that PC?
Or have the same video footage of whatever format, always been
problematic?

Are they specific codec orientated files, such DivX or XviD?

We need to eliminate your graphics card, do DVD's now play OK
when using VLC?

Are there any other problems with that PC that you may have thought
unconnected with the video/wmp issues?

Have you made any changes, such as virtual memory settings?

In Device Manager is anything flagged with an exclaimation or
questionmark?
