Hi,

I've had similar problems. The 'GetEntryAt(-1)' is an indication that
mythtv can not find a particular channel. You might want to check the
log of the mysql server and see which info the backend is requesting or
storing in the database. After investigiating this and reading some
comments on the net, I found the answer to the problem. In my case this
error message meant that the starting channel I entered when configuring
the tv-cards was incorrect. The mysql-log had some messages which
supported this idea. After leaving the field blank, live tv started
without a problem.


I hope this helps,

Cheers,

Max
