I don't have MythTV installed yet - I'm still at the 'testing out my 
hardware' stage.
I want to be able to prove my tuners work independently of MythTV.  
Then,when I install MythTV and can't get them to work with it I will 
know that it's just my inablility to configure a new (to me) and complex 
piece of software thats the problem!
Hence my attempts to get the NOVA-TD500 to work with scan - the most 
basic of DVB tools.
