The MSI TV at nywhere A/D manual suggests that the FM tuner is optional.  
The card has a female TV (analogue + DVB-T) connector, an (optional?) 
male FM radio connector and a multipurpose connector (with custom 
adapter that has many sockets).  

It is possible to connect the cable to the FM radio socket and 
wonder why it does not display TV.

Using the free ati/radeon driver on a 9250 series PCI card - so I should 
be safe on that point.  On the other hand I'm not, so happy about the 
motherboard.

It was tvtime that seemed to be miss behaving, but it is OK now.  

There are three internal connectors on the MSI TV at nywhere A/D card, 
none of which are mentioned in the manual.  

There is an "audio out" connector, which was empty yesterday, but is 
now connected to the "optical drive audio connector" on the motherboard.  
There is now sound with tvtime.  

There is also a "CD in" connector and an unlabeled ten pin connector.
