Yes, I think you're right. I hadn't noticed this but I do have the 
latest version. I know this because I get nagged at boot about how I'm 
using dangerous, non-production, experimental drivers. :-)

I have been browsing the source a fair bit and playing with v4l2-ctl to 
see what can be changed. It seems there is a lot unfinished wrt v4l2 
controls. Some functions even seem to do nothing and/or return zero 
regardless of inputs.

One thing I was kind of hoping to tweak was encoder resolution. It seems 
to be stuck on 720x576 and I can't see a way to change this. The major 
problem is no info on how to control the hardware or even what it is 
capable of doing. Seems like Hauppauge keep this info locked up tight. 
Bah! Closed IP about hardware is a perennial problem for Linux. :-(
