If you can't identify them with a scan, you'll need to edit the  
XMLTVID's of each channel to match what channel it is in your listing  

No idea about your card-specific questions. Try running some dvb tools  
to check for signal to noise ratio, signal strength, etc and see if  
that's why it's not getting a lock immediately.
