John,

It looks like it's a problem with the way your 350 card's inputs are
defined within mythtv. Note the error:

2005-05-11 16:39:25.586 ChannelBase: Could not find input: Television
on card when setting channel 3

When asking for LiveTV myth is timing out after failing to find the
input, giving you the unresponsiveness you are seeing. Also, make sure
the before the backend starts up, the ivtv driver is loaded also. You
could experiment by turning off the mythbackend service, manually
modproding the ivtv driver, then restarting mythbackend to see if this
alleviates the problem.

If this doesn't help, it may worthwhile to either delete the capture
card details in mythtvsetup and re-enter the details, taking care to
ensure the inputs on the card are correct and assigned to the right
channels lineup.
