[linux-dvb] Problem with Nova-T usb stick - any ideas?

Further to my previous post, I've loaded the modules with debug info 
turned on and got some more diagnostics. If anyone can help or wants 
more, or knows whats this means I'm happy to help further. Below are my 
three scenarios with appropriate command lines and kernel messages.

Firstly I have xine, which will work and correctly tune and allow me to 
watch TV
Secondly there is dvbtune, which looks like it locks and tunes correctly
Thirdly is the tzap output, I want to use tzap along with dvbstream to 
record using mythtv or freevo.

I don't really know whats wrong or where to begin, but I'm happy to 
learn and help because I've got the stick now and I want it to work!

I am using fedora core 5, kernel  2.6.18-1.2239.fc5 on a via eden 
sp13000 motherboard and chip combo.

When using xine it successfully tunes and I can watch tv just fine, I 
get the following log info:

When I run dvbtune, I can get the following, which seems to tune correctly:

But trying to use tzap I get the following, and the output from tzap 
looks like it doesn't tune at all
