Hi there,
Could I possibly trouble you by asking that you post in plain text?
When I received your email the text displayed very small on my
system, a size not conducive to reading with my blurry early-morning
eyes, and it was an inconvenience to reach for the keyboard &
increase the font size. If you add mythtv-users at mythtv.org to your
Outlook address book then I think there is an option to "send to this
recipient only in plain text".

I _think_ this indicates that your graphics card drivers don't
support hardware acceleration.

Have you installed the binary nVidia drivers?
As Mr Wilson observes "if you didn't know about the binary nvidia
driver, I can almost guarantee you're using the open source nv
driver, which is utterly craptastic ..."
