i'll try my best to expand on things.

first off the nvidia icon/shortcut in the taskbar to the nvidia application that allows you to change the settings. this does not need to be launched at startup, its only a gui for users to have quick access to the settings.

no not nvidia experience as i have not installed that but even so nvidia have also put a 'call back' that reports problem and IIR is hidden in the help tab at the top of the page on the taskbar icon/shortcut. it must be constantly trying to do an ET.. lol

now onto the networking. i have set a static ip address with no DNS. this allows network access for homegroup but no internet access. i use homegroup to map network drives so i can rip from the upstairs computer to the HTPC downstairs. think of it as a very basic NAS without the expense.
i dont want internet access to the HTPC as i dont want updates destroying my setup. now this is where microsoft get sneaky, they now use other computers on a connected network to 'share' updates so you have to turn that off as well.

i made more progress last night regarding setting custom profiles but could not get it to work properly. i have discovered that the 23hz profile is not communicating with the nvidia drivers properly e.g. the 23hz profile in madvr is showing up as 24hz profile in the nvidia app. i only discovered this at the very end of the night so will be doing more investigation tonight but my sneaky suspicion is that if i set madvr 'switch to' to 24hz instead of 23hz it will use the custom profile set in nvidia which is mistakenly named then i'm hoping that it will use that profile but actually be 23hz.
