Thanks for the replies - for the record I have been removing the power when restarting to fix any issues. that is one reason why it is a pain. If I could just restart or even stop the backend and unload/reload the drivers, then I could do it remotely, or even script it.<br>
<br>I have made Alex's suggested changes to the multiplex information on the database. I removed all the channels and existing multiplexes and started again to ensure I was "clean". Also, rather then bugger about with the db directly I have made the changes in the transport editor in the backend setup. I will see how I get on.<br>
<br>I already have quick tuning enabled - I may turn it off if the transport changes do not improve things.<br><br>thanks so far.<br><div class="gmail_quote"><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
