[Martin Saldert <9e@evil-zone.com>]

Hi all.

I have a problem with my Nova-T card.
I cant change channel in Mythtv. ( i can if the channels are on the same 
frequency )

I have a output of the problem:

2004-06-17 22:58:22 Couldn't read data from the capture card in 15 
seconds.  Game over, man.

You can see that the first tune is ok.
Then a bit down i change channel,
And all the errors comes.
If i go back to the Mythtv GUI and selects watch tv again it tunes 
emediatly.
So all channels tune fast when i come from the MythTv gui.
But changing channel to one of them does not work :-(

Any ideas?
I have searched the MythTv and DVB mailinglists but havent found anything.

I use a week old DVB from CVS.
