[linux-dvb] Compro VideoMate T750

I have recently been given a Compro VideoMate T750 to get working with 
Linux.  Unfortunately it is not yet supported by the v4l-dvb drivers.

This is an Australian card has the following features:
- Analog TV Tuner (PAL-BG?)
- Analog TV Capture (SVideo & Composite)
- FM Radio
- IR
- DVB-T * 2

I have tested a few similar cards using the Mercurial drivers and the 
analog capture works.  I have not been able to get the DVB working 
(which is what I want the most).

I am prepared to do whatever testing is required to get this working but 
I was hoping there was a saa7134 expert who could suggest the best way 
to go about it.

The card is currently installed in my linux dev box but I can pull it 
and/or stick it in a windows box if necessary.

I have used btspy under windows in the past to figure out bt878 based 
cards.  Is there a similar saaspy?

Any help would be much appreciated.
