[Mark Preston <emp2008@xxxxxxx>]

Without MythTV's frontend running, the Launchpad Bug reporter came up on
screen today. I had to twice enter my Linux Admin password, and then and
only then would this bug be reported. While this bug has been triaged as
being of medium importance, I suggest it is worse (higher importance).
Ever since MythTV has become part of my auto-downloads through the
Ubuntu Update Manager, my hard drive spins furiously and the CPU had
insane load averages of 15 : 12 : 8. I have a quad core cpu. This
conflict even causes the mouse cursor to disappear from the screen and
no amount of mouse movement "finds" it. What is even more confusing is
that I am taken to a Launchpad page to select from several bugs and I
have NO WAY of knowing which to select. So, even though I'm in
ignorance, I have selected this one. By the bye: the Launchpad bug
report took several minutes to populate it's report and send it along
here. As my upload speed is 76K, that's a lot of upload. In the
megabytes.
