Since I have plenty of CPU power, I have reverted to the HIGH QUALITY profile which has performed very well.  I'm running Ubuntu 9.04 >and it appears that all videox devices are added with the group VIDEO which has rw access.  My mythtv user is a member of the VIDEO group.

Hi again Ken,

 Yes, looks like my permssions were the same as yours to start with (before I changed them to 775). VDPAU I haven't tried yet, as stated earlier, but I'm using the NVidia 190.x driver from JYA's repo.
The kernel level module options are just options lines which you put in a file under /etc/modules.d/  Yopu'll see other files there which you can check for syntax. The options themselves I found in the WIKI (setting default audio and video inputs etc.) I've changed mine back to s/pdif and component now, but will revert to rca/component for the next tests (and in the backend setup).

I only have a 720 TV so am sticking to 720p anyway for now, although cable will spit out a max of 1080i if I ask it to. To be honest I'd rather have the slightly lower res, and not have to bother with the deinterlacing anyway.
