[mythtv-users] random livetv stalls

Follow up on my original email.

It happened again right after I sent the last email.  It stayed frozen
until the time changed to the very top of the hour.  Then everything
started working again just like I had restarted it.  This must be related
to the few seconds pauses I get at the top and bottom of every hour?  I had
been getting those paused for months and just lived with it.

One other request.  If someone could point me to a how-to correctly reply
to this list using gmail I will be eternally grateful.
