I've looked at this patch and it has significant changes to dvb_frontend 
and other user facing API's. It's not something that can be merged as 
is, without major cleanup.

It would be possible to extract, cleanup and merge the demodulator/card 
driver, probably.

I don't have this hardware so I probably wouldn't work on the card 
specific driver.

I will use this for DSS reference though, thanks.

That's interesting, because I've previously thought that the kernel 
demux didn't understand 144 (?) byte packets.

Does this actually work, and are the regular DVB tools giving you 144 
transport packets? Which applications do you use for analysis and/or 
playback?

The HVR4000 silicon supports DSS but I've never enabled it, if the 
applications and kernel support are maturing then I'll certainly do 
this. Why not, right?

Let me know.

Regards,

Steve
