I hope you didn't take offence at the comments about getting in the way of 
progress. The sarcastic British humour can be a bit dry sometimes!!!

Don't get me wrong, I agree that you should continue to supply a version... I 
did notice that in the current ivtv build instructions, it is suggested that 
you build against your kernel header (if available) and only copy the 
videodev2.h file from the utils area to the driver area if needed.

Does the Myth version of this header match the ivtv supplied version? I had 
more problems when using the ivtv supplied header (to the point of hanging the 
backend) than I did with the v4l2 header (which just broke brightness/contrast)

Could MythTV look in /usr/src/linux/... for a suitable file and use it if 

More simply, perhaps I could offer a paragraph for the HOWTO on this??? Just 
let me know.

Of course, then the v4l2 guys would come along and break some other binary 
compatability :-)

Thanks for the reply.
