[mythtv-users] Channels that don't broadcast all the time; DVB-T radio channels.

[Greg]

Hi, 
I've more or less got a working MythTV box (subject to testing), running with 
a Hauppauge Dec-2000T over USB.
I'm in the UK, and on Freeview, there are some channels that don't broadcast 
all the time (BBC Three and Four, abc1, CBBC/CBeebies etc.). When they're 
broadcasting it all works fine, but when they're not and you try and tune to 
them with mythfrontend, the frontend times out after trying for 15 seconds 
and drops back to the menu, without giving you chance to change the channel. 
This leaves you stuck on a channel.
Is there a way to change the channel without getting any data first? 
Is there a more elegant solution to this problem?


Almost unrelatedly, there are also several Radio channels I could pick up 
(just an Audio ID, no Video ID), but myth doesn't seem to like not having any 
video, so tuning to these channels has much the same effect as above.

Am I missing something?
I can get verbose outputs later (at work now), but they're mostly along the 
lines of "Warning: Got no data from card in 1 second" or "No data for 15 
seconds, Game Over."
Thanks,
Greg Manning.
