[mythtv] WinTV Nova-S CI PCI bug?

[Mattia Martinello]

Hi,
I'm trying to setup Mythtv with Hauppauge WinTV Nova-s CI PCI DVB card.
I can see the starting channel, but I can't switch to another channel.
I can scan for channel and I can see the start channel I configured in 
Input Connections, but I cannot switch channel to channel.
If I select the channel number 1 as start channel I can see it in 
mythfrontend, but I can't switch to channel number 2 (I get only a 
blue-black screen).
If I select the channel number 2 as start channel I can see it it, but I 
can'it switch to channel number 1.

These are the Mythbackend logs when I try to switch to another channel:
